When producing PI heaters, adhesive tape selection is more than a minor detail — it defines bonding strength, heat resistance, and long-term reliability. The right tape keeps the heater stable even under continuous heating cycles.
Different applications require different adhesive types. Some customers focus on high-temperature resistance, while others care more about odor control or material compatibility. Let’s explore the commonly used adhesive tapes and their unique advantages.
The most frequently used adhesive tapes in PI heaters include:
Among these, 3M467, 3M468, and Crown 513 are the standard options for most PI heater manufacturing. Others like 3M9077 or Tesa series are chosen based on special customer needs.
Both 3M467 and 3M468 are widely recognized for their reliability and performance. They are double-sided acrylic adhesive tapes suitable for bonding flexible circuits and metal foils.
These two models can withstand temperatures up to 150°C in continuous operation. They perform well in typical environments such as battery heating, instrument panels, and automotive defogging systems.
Since both are without a base layer, they may emit slight odors under high heat. Still, they remain stable and cost-effective for standard industrial use.
3M9077 is a high-temperature resistant adhesive tape designed for applications requiring cleaner bonding and minimal odor. It’s a base-layer type tape, meaning it contains a stable carrier film that improves handling and reduces adhesive residue.
Although 3M9077 has a higher cost compared to 3M467 or 3M468, it performs well under strict environmental or cleanliness requirements. It’s especially suitable for medical, laboratory, or precision heating systems where air quality and odor sensitivity matter.
If a customer emphasizes “low odor” or “clean-room use,” 3M9077 is the best recommendation.
Crown 513 is another reliable adhesive tape often used when customers have no special odor or temperature requirement. It’s a base-layer adhesive with a total thickness of 0.12mm, providing strong bonding and mechanical strength.
This tape is ideal for products that operate under moderate temperatures or do not experience prolonged heating. Its stable performance and economical cost make it the go-to choice for many general heater applications.
These adhesive tapes are often selected for specific use cases or customer preferences:
While they may not be standard for every PI heater, they provide flexibility for customized requirements.
Choosing the correct adhesive tape depends on three main factors:
1. Operating Temperature:
2. Environmental Conditions:
3. Cost and Performance Balance:
Using the wrong adhesive tape may lead to peeling, air bubbles, or odor release during high-temperature use. However, these issues are usually preventable with proper material selection and surface preparation.
Always match the adhesive tape’s temperature rating and material compatibility with your heater’s working environment. This ensures long-term bonding and reduces maintenance.
A client producing precision heating elements for lab instruments required strong adhesion with zero odor during operation. After evaluating several options, Danyu Electronics recommended 3M9077 due to its base layer structure and clean bonding properties.
The result was excellent. The heater maintained adhesion at 180°C without any visible aging or odor release. The customer later standardized 3M9077 for all their high-end heater products.
Danyu Electronics provides end-to-end support for PI heater design, material selection, and production. Our team helps customers choose the right adhesive tape based on real application data.
We follow strict quality management systems, including ISO9001, ISO13485, IATF16949, and AS9100D. Every heater undergoes full traceability through our MES system, ensuring material consistency and safety.
Our engineering team can assist you in testing bonding strength, temperature resistance, and odor control, helping you find the most suitable adhesive tape for your project.
1. What is the temperature limit for 3M467 and 3M468?
Both tapes can withstand up to 150°C for continuous use.
2. Why does 3M9077 have less odor than other types?
It contains a base layer that stabilizes the adhesive and prevents odor during heating.
3. What is the thickness of Crown 513 adhesive tape?
Crown 513 has a total thickness of 0.12mm.
4. Can all adhesive tapes be used in high-temperature environments?
No. Always check the adhesive’s rated temperature and application guidelines before use.
5. Can Danyu Electronics help select adhesive tape for custom heaters?
Yes. Our engineers analyze your temperature, voltage, and surface material to recommend the ideal tape.
