UL high temperature resistant thermal conductive tape

UL high-temperature resistant thermal conductive tape combines high temperature resistance and efficient thermal conductivity, suitable for high-frequency scenarios such as 5G millimeter waves, providing reliable thermal conduction and electromagnetic protection to ensure stable operation of equipment under harsh working conditions.

Production process:

1. Substrate preparation: Mix and stir high-temperature resistant materials such as polyethylene terephthalate (PET) and polyimide (PI), dry and shape to form a flexible and temperature resistant substrate.
2. Preparation of adhesive components: A thermosetting adhesive is generated by reacting phenolic resin with polyvinyl butyral, and mixed with lignin grafted acrylic pressure-sensitive adhesive to form an adhesive layer that combines heat resistance and bonding strength.
3. Thermal conductivity network construction: Nickel stearate dispersed metal nickel powder is used to form a uniform thermal conductivity pathway in the colloid, avoiding performance degradation caused by local overheating.

4. Coating and Forming: Apply adhesive components evenly onto the surface of the substrate, control the coating thickness and uniformity, and form a composite tape with thermal conductivity and adhesive function through curing process.
   

Precautions for use:

1. Surface pretreatment: Before pasting, the substrate surface needs to be cleaned to remove oil stains, dust, and other impurities, ensuring that the tape is in full contact with the contact surface.
2. Pressure and curing: Appropriate pressure should be applied during bonding to promote the flow of colloids and the discharge of air. If necessary, hot pressing technology can be used to accelerate curing.
3. Environmental control: Avoid using in damp, dusty, or corrosive gas environments to prevent deterioration of tape performance.
4. Storage conditions: Store in a cool and dry environment, avoid direct sunlight and high temperatures, and regularly flip the tape roll to prevent adhesion.
5. Operating standards: Do not excessively stretch or twist the tape to prevent the thermal network from breaking; Seal the packaging promptly after use to prevent performance degradation.
