Colored high-temperature resistant adhesive tape is made by coating a specific substrate (such as polyimide, polyester film, etc.) with high-temperature resistant adhesive and adding pigments. It has the characteristics of high temperature resistance, electrical insulation, chemical corrosion resistance, stable mechanical properties, and color identification, and is widely used in the fields of electronics, automotive, aerospace, etc. The following is a detailed analysis of its performance:

1、 High temperature resistance performance

Temperature resistance range: Colored high-temperature resistant tape can usually maintain stability in high temperature environments ranging from 120 ℃ to 300 ℃, and some special tapes can even withstand higher temperatures. For example, the long-term temperature resistance of polyimide (PI) based adhesive tape can reach 220 ℃ to 260 ℃, and the short-term temperature resistance can reach around 300 ℃.

Thermal stability: At high temperatures, the tape will not melt, deform, or peel off, ensuring that it can still perform well under high-temperature working conditions.

2、 Electrical insulation performance

High insulation performance: Colored high-temperature resistant tape has excellent electrical insulation performance, low dielectric constant, high breakdown voltage, and is suitable for insulation protection in the electronics industry.

Low electrolysis: In high temperature and high humidity environments, the tape can still maintain good electrical insulation performance, reducing the occurrence of electrolysis phenomena.

3、 Chemical corrosion resistance performance

Acid and alkali resistant: Tape can withstand a certain concentration of acid and alkali solution erosion, suitable for corrosive environments in chemical, electronic and other fields.

Solvent resistance: It has good tolerance to various organic solvents and is not easily dissolved or damaged by solvents.

4、 Mechanical performance

High tensile strength: Tape has high tensile strength and can withstand certain external forces without easily breaking.

Good tear resistance: When subjected to tearing force, the tape can maintain good integrity and is not easily torn.

Wear resistant wiping: The surface of the tape has good wear resistance and can maintain a long service life in a frictional environment.

5、 Other performance

Color identification: Colored high-temperature resistant tape is made into different colors by adding pigments, making it easy to identify and distinguish during the production process.

Good adhesion: The tape has good adhesion and can firmly adhere to various material surfaces without leaving any residue after tearing off.

Environmental friendliness: Some colored high-temperature resistant tapes are made of environmentally friendly materials, which meet environmental requirements and are harmless to the environment and human health.
