Related RFID products
Standard RFID labels are not designed for every industrial environment. In automotive manufacturing, electronics assembly, industrial laundry, sterilization, tire production and metal processing, RFID tags may be exposed to high temperatures, pressure, chemicals, vibration and repeated thermal cycles.
When ordinary RFID labels cannot survive these conditions, high temperature RFID tags provide a more suitable identification solution. They combine specialized chips, antennas and protective materials to maintain their physical integrity and identification performance under demanding thermal conditions.
However, choosing a high temperature RFID tag involves more than checking its maximum temperature rating. A tag that withstands 260°C for several seconds is not necessarily suitable for continuous operation at 200°C. Likewise, a tag that survives a heating process may not be readable while it is still hot.
At DO RFID, we provide customized RFID and NFC tags for industrial identification, product traceability and asset management. Our product options include flexible FPC tags, PPS tags, epoxy-sealed NFC tags and UHF spring tire tags.
This guide explains how high temperature RFID tags work, how to compare different constructions, and what industrial buyers should verify before placing a bulk order.
What Are High Temperature RFID Tags?
High temperature RFID tags are radio frequency identification devices designed to withstand elevated temperatures during operation, storage or industrial processing.
Like conventional RFID products, they generally contain three main components:
- RFID chip: Stores identification information and communicates with a compatible reader.
- Antenna: Receives the reader’s signal and transmits the tag’s response.
- Protective structure: Protects the chip and antenna from heat, moisture, chemicals, mechanical stress and other environmental conditions.
The main difference is the engineering of the materials and assembly.
A standard paper or PET RFID label may lose adhesion, deform or suffer antenna damage when exposed to industrial heat. High temperature versions use more suitable substrates, encapsulation materials, adhesives and protective housings.
Depending on the design, high temperature RFID tags can be manufactured using FPC, PPS, ceramic, FR4, PTFE, PEEK, epoxy-sealed structures or other heat-resistant materials.
They are available in LF, HF and UHF configurations, although not every material and chip combination is suitable for every frequency or application.

Three Temperature Ratings You Must Understand Before Buying
One of the most common mistakes in high temperature RFID procurement is treating every temperature figure as an operating temperature.
A product may advertise resistance to 260°C, but that figure could describe a short manufacturing exposure rather than continuous operation.
For accurate selection, distinguish three temperature conditions.
1. Continuous Operating Temperature
This is the temperature range in which a tag is designed to function under its specified operating conditions.
For an RFID application, functioning means more than avoiding physical damage. The chip, antenna and encapsulation must continue to provide acceptable communication performance.
For example, some DO RFID FPC NFC products specify a normal operating range of -30°C to +85°C, while separately listing higher process-temperature resistance.
These two specifications describe different conditions.
2. High-Temperature Exposure or Survival Temperature
Some RFID tags are designed to pass through an industrial heating process and be read afterward.
Examples include:
- Paint curing and drying processes
- Industrial pressing
- Solder reflow
- Sterilization processes
- Heating and curing during component manufacturing
In these applications, a tag may tolerate a high temperature for a specified duration, cool down, and then return to normal RFID operation.
This does not automatically mean that it can communicate with a reader while exposed to the same temperature.
3. Short-Term Peak Temperature
A short-term peak rating describes the maximum temperature a tag can tolerate for a limited period.
For example, a product rated for 200°C over two hours and 260°C for 10–30 seconds has two different exposure conditions.
It should not be described as a tag capable of continuously operating at 260°C.
Temperature Rating Comparison
| Temperature Specification | What It Means | What Buyers Should Confirm |
|---|---|---|
| Operating temperature | Normal functional temperature range | Can the tag be read and written reliably? |
| Exposure temperature | Temperature the tag can withstand during a process | How long is the exposure permitted? |
| Peak temperature | Brief maximum temperature | Is the stated duration sufficient for the actual process? |
| Storage temperature | Permitted temperature while stored | Does long-term storage affect the tag? |
| Thermal cycling | Repeated heating and cooling | How many cycles have been tested? |
| Hot-state reading | RFID communication while the tag is hot | Has communication performance been tested at the actual process temperature? |
For industrial projects, we recommend providing the complete temperature profile to the supplier rather than asking only, “What is your maximum temperature?”
A useful temperature profile includes the peak temperature, exposure duration, cooling time, number of cycles and whether reading is required during or after heating.
Main Types of High Temperature RFID Tags
Different industrial environments require different tag structures. A compact electronic component, a metal production fixture and a washable textile asset will not necessarily use the same RFID construction.
1. FPC High Temperature RFID Tags
FPC stands for Flexible Printed Circuit. FPC RFID tags use a thin flexible circuit structure, making them suitable for applications where installation space is limited.
Their small size is particularly useful when tags need to be embedded into equipment, components or packaging.
Depending on chip selection and design, FPC tags can support HF/NFC applications and other customized identification requirements.
Advantages:
- Very thin construction
- Compact dimensions
- Suitable for embedded applications
- Flexible design for space-constrained products
- Supports customized chip and antenna configurations
DO RFID offers small FPC NFC products, including:
| Product | Size | Temperature Specification | RFID Details |
|---|---|---|---|
| 5 mm FPC NFC Tag | 5 mm diameter; 0.05–0.07 mm thick | 200°C / 2 hours; 260°C / 10–30 seconds | NXP ICODE SLIX-L, 13.56 MHz |
| 8 mm FPC NFC Tag | 8 mm diameter; 0.05–0.07 mm thick | 200°C / 2 hours; 260°C / 10–30 seconds | HS01, 13.56 MHz |
Both product pages list a normal operating temperature of -30°C to +85°C and a reading distance of approximately 1–10 mm, depending on the reader and environment.
These products are intended for applications requiring a very small HF identification device and specified short-term process-temperature resistance. They should not be treated as long-range UHF tags.
Product details:
2. PPS High Temperature RFID Tags
PPS (Polyphenylene Sulfide) is an engineering thermoplastic used in industrial environments requiring heat resistance and chemical durability.
PPS RFID housings are often selected for reusable industrial assets, laundry tracking, equipment identification and applications involving frequent cleaning.
Compared with conventional thin paper labels, a rigid PPS tag offers greater structural protection.
Advantages:
- Durable housing
- Good resistance to many industrial chemicals
- Suitable for reusable identification systems
- Supports compact industrial tag designs
- Can be configured with HF or NFC chips
DO RFID’s DO-PPS20 is a 20 mm PPS NFC tag equipped with an NXP NTAG216 chip.

The product is suitable for industrial laundry and asset identification projects where a durable NFC tag is required.
It is important to distinguish the product’s published temperature resistance from its normal operating temperature. Buyers who require continuous RFID operation at temperatures approaching 180°C should request additional technical confirmation and application testing.
See our 20 mm PPS NFC Tag with NXP NTAG216.
3. Epoxy-Sealed High Temperature RFID Tags
Epoxy-sealed RFID tags use encapsulation to protect electronic components against moisture, dirt and mechanical damage.
Depending on the design, the enclosure can be combined with ABS, PPS or another suitable supporting structure.
This construction is useful for applications involving repeated handling, cleaning or exposure to environmental contaminants.
DO RFID offers a 13.56 MHz NFC smart button tag with an NTAG213 chip and an epoxy-sealed ABS/PPS structure.
| Parameter | Specification |
|---|---|
| Product Type | NFC Smart Button Tag |
| Chip | NTAG213 |
| Frequency | 13.56 MHz |
| Protocol | ISO/IEC 14443A |
| Dimensions | 23 mm diameter × 4.5 mm |
| Material | Epoxy-sealed ABS/PPS |
| User Memory | 180 bytes |
| Operating Temperature | -30°C to +85°C |
| Process Temperature Resistance | 200°C / 2 hours; 260°C / 10–30 seconds |
| Reading Distance | Approximately 1–10 mm, reader dependent |
This product is worth considering for industrial identification, equipment maintenance, laundry-related asset management and applications requiring a protected NFC form factor.
However, epoxy encapsulation alone does not guarantee high-temperature performance. The entire assembly, including the chip, antenna, supporting material and resin, must be evaluated together.
Explore our Epoxy-Sealed NFC Smart Button Tag.
4. Ceramic and FR4 High Temperature RFID Tags
Ceramic and FR4 structures are commonly used in industrial RFID products that need a rigid, protective construction.
Ceramic tags can be suitable for demanding thermal and mechanical environments, while FR4-based tags are used in compact PCB-style assemblies.
These products are particularly relevant to applications involving metal fixtures, industrial tools and production equipment.
Typical advantages include:
- Rigid construction
- Compact form factors
- Potential suitability for metal-mounted designs
- Mechanical protection for embedded electronics
- Compatibility with selected UHF chip and antenna configurations
Actual temperature resistance varies by design. A ceramic tag rated for a certain exposure temperature should not be assumed to have the same rating as every other ceramic product.
When selecting ceramic or FR4 tags, confirm the complete product datasheet, mounting surface, exposure duration and required reading distance.
5. UHF High Temperature RFID Tags
UHF RFID tags are widely used when the system needs longer reading distances or bulk identification.
In industrial manufacturing, they can identify tools, components, containers, fixtures and production carriers as they move through different workstations.
A high temperature UHF tag should be evaluated not only for its thermal rating but also for:
- Regional operating frequency
- EPC Gen2 / ISO/IEC 18000-63 compatibility
- Antenna design
- Mounting surface
- Required read range
- Performance after thermal exposure
DO RFID also offers an embedded UHF spring tire tag designed for tire identification and lifecycle traceability.
According to its published specifications, the tag uses a steel-wire structure measuring 84 × 1 mm, an Alien Higgs-3 chip and EPC Gen2 communication. Its listed operating and storage temperature range is -40°C to +200°C, with a stated reading range of 2–3 meters.
The tag is designed to be embedded during tire manufacturing rather than attached as an ordinary surface label.
See our UHF Spring Tire Tag.
How to Choose the Right Material for a High Temperature RFID Tag
Material selection affects more than the maximum temperature rating. It also determines the tag’s dimensions, flexibility, mounting method, mechanical protection and suitability for repeated industrial use.
| Material or Structure | Typical Characteristics | Suitable Application Types | Key Consideration |
|---|---|---|---|
| FPC | Thin and flexible | Embedded identification, compact components | Verify process exposure and antenna protection |
| PPS | Rigid engineering plastic | Laundry, equipment and industrial assets | Confirm operating and exposure ranges separately |
| Epoxy Sealing | Protective encapsulation | Buttons, compact asset tags | Resin and internal components must be thermally compatible |
| Ceramic | Rigid, heat-resistant construction | Industrial tools and selected metal assets | Mechanical impact and mounting need evaluation |
| FR4 | PCB-based structure | Compact industrial UHF tags | Verify long-term thermal stability |
| PTFE | Chemical and heat-resistant material | Harsh industrial environments | Confirm complete product construction |
| PEEK | High-performance engineering plastic | Specialized high-temperature applications | Higher material and manufacturing costs may apply |
| Metal Housing | Strong mechanical protection | Heavy industrial equipment | Antenna design must support RFID operation on metal |
No single material is automatically best for every high-temperature RFID application.
For example, a thin FPC tag may be preferable for embedding inside a small component, while a rigid ceramic or metal-housed UHF tag may be more appropriate for a large industrial tool.
The correct choice depends on the process, asset, mounting space and RFID system.
High Temperature RFID Tags for Different Industrial Applications
1. Automotive Manufacturing
Automotive production involves multiple processes, including component assembly, painting, drying and quality inspection.
Parts, tools and returnable production carriers may need to be identified as they move through different manufacturing stages.
High temperature RFID tags can help automate work-in-progress identification and production traceability.
A suitable tag should be selected according to the actual production route.
For example, a component exposed to a short heating cycle may use a different tag from a metal fixture repeatedly passing through a paint curing process.
Recommended selection considerations:
- Temperature profile at each production stage
- Metal or non-metal mounting surface
- Required reading distance
- Tag thickness and available installation space
- Repeated thermal exposure
- Required identification data
2. Electronics Manufacturing and Solder Reflow
Electronics manufacturing may involve solder reflow, curing and other localized high-temperature processes.
Small tags are often preferred because available installation space is limited.
FPC NFC tags can be considered for selected embedded or process-identification applications where their thermal exposure specifications match the manufacturing profile.
Before integration, manufacturers should verify:
- Whether the tag is exposed to the complete reflow cycle
- Whether the antenna and chip remain functional afterward
- Whether the tag is embedded before or after heating
- Whether read/write access is required during production
- Whether the selected adhesive or encapsulation material is compatible
A tag’s ability to survive a short heat exposure should not be interpreted as proof that it can be read during that exposure.
3. Industrial Laundry and Textile Management
Industrial laundry operations expose identification devices to washing, drying, pressing, pressure extraction and chemical cleaning.
Ordinary adhesive labels are not suitable for many reusable textile-tracking applications because they may detach or deteriorate.
Specialized laundry tags are designed with more suitable materials and attachment methods.
Common installation options include sewing, heat sealing and embedding.
DO RFID supplies Laundry RFID Tags and PPS NFC tag options for reusable textile and asset identification.
For these projects, buyers should check not only heat resistance but also:
- Washing temperature
- Drying temperature
- Water extraction pressure
- Chemical exposure
- Number of washing cycles
- Attachment strength
- Reading performance on wet and dry materials
A washable RFID tag and a high-temperature process tag are not automatically interchangeable. The correct model must match the entire laundry cycle.
4. Tire Manufacturing
Tires are exposed to high temperature, pressure and deformation during manufacturing and throughout their service life.
Traditional labels cannot always remain attached throughout the complete lifecycle.
An embedded UHF spring tire tag provides another way to assign a unique electronic identity to a tire.
The tag can support production traceability, inventory management and identification after manufacturing.
For tire projects, the specification should be validated against the actual curing process, including temperature, pressure, exposure duration and material deformation.
DO RFID’s UHF spring tire tag is designed for embedded tire identification and lists an operating temperature range of -40°C to +200°C.
5. Medical and Pharmaceutical Processing
Medical equipment, reusable instruments and pharmaceutical production assets may pass through cleaning, sterilization or controlled manufacturing environments.
For these applications, compact NFC or HF RFID tags can support identification and traceability.
The selected product must be evaluated against the actual sterilization method, temperature, pressure, moisture and chemical exposure.
Not every high-temperature RFID tag is suitable for autoclaving. A high-temperature resistance rating alone does not establish compatibility with steam, pressure or repeated sterilization cycles.
6. Metal Processing and Industrial Equipment
Metal tools, machinery, pallets and fixtures can present two separate challenges:
- High temperature exposure.
- RFID antenna performance on metal.
A conventional RFID label may not work reliably when attached directly to a metal surface. A dedicated anti-metal structure may be required.
However, an anti-metal rating and a high-temperature rating are two different specifications. Buyers should confirm that the same tag model has been validated for both requirements.
For metal-mounted applications, explore our UHF RFID Anti-Metal Tags and our guide to RFID Tags for Metal Surfaces.
Does a High Temperature RFID Tag Work While It Is Still Hot?
Not necessarily.
This is one of the most important questions to ask before purchasing industrial RFID tags.
Some tags are designed to survive a heating process and become readable again after cooling. Other specialized solutions are engineered for identification while the asset remains hot.
These are different product requirements.
During high-temperature exposure, the performance of the chip, antenna and surrounding materials may change. The reader-to-tag communication performance can also be affected by the equipment, installation position and environmental conditions.
A tag that passes a thermal survival test is not automatically qualified for hot-state RFID reading.
Two Common Application Scenarios
| Application | Required RFID Function | Suitable Evaluation |
|---|---|---|
| Tag passes through an industrial oven | Identification after cooling | Test the tag before and after the heating process |
| Tag must be identified while still hot | RFID communication during exposure or immediately afterward | Conduct hot-state reading tests at the actual temperature |
| Tag passes through repeated heating cycles | Long-term identification reliability | Test multiple representative cycles |
| Tag is mounted on hot metal machinery | Stable reading on a conductive surface | Test on the actual metal material and mounting position |
For projects that require reading while the asset is still hot, tell the supplier this requirement at the beginning.
Do not assume that a product’s peak temperature rating also represents its hot-state communication capability.
High Temperature RFID Tags vs. Standard RFID Tags
The difference between ordinary RFID labels and high temperature RFID products lies mainly in their materials, protective structures and validated environmental performance.
| Comparison Factor | Standard RFID Tags | High Temperature RFID Tags |
|---|---|---|
| Substrate | Paper, PET, standard PVC or similar materials | FPC, PPS, ceramic, FR4 and specialized structures |
| Thermal Resistance | Suitable for normal operating environments | Designed for specified high-temperature conditions |
| Encapsulation | Basic protective layer or label structure | Specialized sealing or protective housing |
| Industrial Exposure | Limited suitability for extreme processes | Can be designed for heat, cycling and selected harsh environments |
| Mounting | Usually adhesive | Adhesive, sewing, embedding, screw or other mechanical fixing |
| Application | Retail, logistics, access control | Manufacturing, automotive, laundry, sterilization and asset tracking |
A high temperature tag may cost more than a standard RFID label because of its material, structure, chip selection and manufacturing requirements.
However, the total project cost should also include tag replacement, manual identification, production downtime and traceability errors.
For businesses operating demanding industrial processes, a suitable tag can help reduce repeated identification problems and maintenance work.
How to Test High Temperature RFID Tags Before Bulk Ordering
For B2B procurement, sample testing is one of the most important steps.
A tag that works on a supplier’s test bench may behave differently when mounted on an actual production component.
We recommend validating the following points before approving mass production.
1. Confirm the Thermal Profile
Record the actual process conditions.
| Test Parameter | Information Required |
|---|---|
| Peak Temperature | Highest temperature reached |
| Exposure Duration | Time spent at each temperature |
| Heating Rate | How quickly the temperature increases |
| Cooling Rate | How quickly the asset returns to normal temperature |
| Cycle Count | Number of heating and cooling cycles |
| Reading Condition | During heating, immediately afterward or after cooling |
A complete process profile is much more useful than a single maximum-temperature figure.
2. Test RFID Functionality Before and After Heating
Record the tag’s initial performance before thermal exposure.
After the test, check whether it can still:
- Be detected by the intended reader
- Return the correct unique identifier
- Complete read/write operations where supported
- Maintain the required communication distance
- Work consistently across repeated scans
For tags designed for post-process reading, the test should follow the intended cooling procedure.
3. Check Physical Integrity
Inspect the tag after exposure.
Look for:
- Cracks or deformation
- Resin or housing damage
- Antenna separation
- Delamination
- Surface discoloration
- Adhesive failure
- Changes in dimensions
A tag may still respond to a reader even when its housing has suffered damage. Mechanical inspection is therefore also important.
4. Repeat Thermal Cycles
Some industrial assets pass through the same heating process many times.
For these projects, one successful heat exposure is not enough.
Test multiple samples through the expected process cycles, then compare their read performance and physical condition.
5. Test on the Actual Installation Surface
For metal applications, test the tag on the intended metal material.
Steel, stainless steel and aluminum components can produce different RF conditions, while curvature and installation position can also affect performance.
For UHF applications, test with the intended reader and antenna configuration.
DO RFID provides RFID Readers and RFID Handheld Readers for RFID identification and data collection. The selected reader should match the tag’s frequency and protocol.
How to Choose the Right High Temperature RFID Tag
Before selecting a product, define the complete application instead of choosing solely by temperature rating.
The following checklist can help procurement teams and system integrators prepare a technical inquiry.
| Selection Item | Questions to Answer |
|---|---|
| Application | Is the tag used for automotive, laundry, electronics, tire manufacturing or asset tracking? |
| Frequency | Do you require LF, HF/NFC or UHF? |
| Chip | Which chip model or memory configuration is required? |
| Operating Temperature | At what temperature must the tag function normally? |
| Process Exposure | What is the maximum temperature and exposure duration? |
| Thermal Cycling | How many heating and cooling cycles are expected? |
| Reading Condition | Must the tag be readable while hot or after cooling? |
| Mounting Surface | Will the tag be attached to metal, plastic, textile or another material? |
| Installation | Do you prefer adhesive, screw mounting, sewing or embedding? |
| Read Range | Is close-range NFC identification or long-range UHF reading required? |
| Protection | Is resistance to water, chemicals, dust or mechanical impact required? |
| Quantity | How many samples and production units are required? |
For a custom project, providing these details at the quotation stage helps reduce unnecessary sample revisions.

The most economical tag is not always the one with the lowest unit price. A suitable tag should meet the complete process requirement and maintain reliable identification throughout its intended service life.
Frequently Asked Questions About High Temperature RFID Tags
1. What temperature can an RFID tag withstand?
It depends on the chip, antenna, substrate, encapsulation and product construction. Some industrial RFID tags are designed for approximately 180–200°C exposure, while specialized products can be engineered for higher temperatures. Always check the specified exposure duration and operating range.
2. Can RFID tags withstand 200°C?
Yes. Certain RFID products are designed to withstand 200°C under specified conditions. However, a 200°C exposure rating does not automatically mean continuous operation or reliable reading at 200°C. Buyers should confirm the exact test profile.
3. Can an RFID tag withstand 260°C?
Some specialized FPC and other industrial RFID products specify 260°C resistance for a short period. For example, selected DO RFID FPC NFC products list resistance to 260°C for 10–30 seconds. This is a short-term process specification, not a continuous operating temperature.
4. Can RFID tags work inside an industrial oven?
Some tags can survive industrial oven exposure and be read after cooling. If identification is required while the tag is still inside the oven, a specialized solution and application-specific hot-state testing may be necessary.
5. Which RFID material is best for high temperatures?
There is no universal best material. FPC can be suitable for compact applications, PPS for selected industrial and laundry environments, while ceramic, FR4 and other specialized structures may be used for demanding industrial applications. Select based on the complete thermal and mechanical profile.
6. Are high temperature RFID tags suitable for metal surfaces?
Some are designed specifically for metal mounting, but not every high temperature tag is an anti-metal tag. If your asset is metal, confirm both the thermal rating and on-metal RF performance.
7. What is the difference between heat-resistant RFID tags and washable RFID tags?
Heat-resistant RFID tags are designed to tolerate specified thermal conditions. Washable RFID tags are designed for repeated laundry processes, including water, detergents, extraction pressure and drying. Some tags support both capabilities, but the complete process requirements must be checked.
8. Can high temperature RFID tags be customized?
Yes. Depending on the product structure, suppliers may customize the chip, frequency, size, antenna, material, housing, mounting method and encoding. The customization should be confirmed through technical review and sample validation.
9. Do high temperature RFID tags support long-range reading?
Some UHF high temperature tags support longer-range identification, while HF/NFC products are generally designed for close-range communication. Actual reading distance depends on chip design, antenna, reader power, installation surface and environment.
