Basic Overview and Functional Introduction of Polyimide Tape

Polyimide adhesive tape is made of polyimide film as the substrate and imported organic silicone pressure-sensitive adhesive. It has properties such as high and low temperature resistance, acid and alkali resistance, solvent resistance, electrical insulation (class H), and anti-radiation. It is suitable for shielding wave soldering of electronic circuit boards, protecting gold fingers and high-end electrical insulation, motor insulation, and fixing lithium battery positive and negative poles.

1. Overview of polyimide adhesive tape:

This tape is made of polyimide film as the substrate, coated with high-performance organic silicone pressure-sensitive adhesive on one side, and it can be combined with or without a single-sided fluoroplastic release material. The coating precision reaches ±2.5μm, without scratches, streaks, etc. The tape has good shear properties, and is easy to cut and shape, with excellent high-temperature and solvent resistance.

2. Features and applications of polyimide adhesive tape:

In the electronic and electrical industry, it can be used for insulation binding of H-class motors and transformers with higher requirements, high-temperature coil end binding and fixing, thermocouple protection, capacitors and wire bundling, and other adhesive insulation under high-temperature working conditions.

In the printed circuit board manufacturing industry, it can be used for electronic protection stickers, especially suitable for SMT temperature-resistant protection, electronic switches, PCB board gold finger protection, electronic transformers, relays, and other electronic components that need to be resistant to high temperatures and moisture. Polyimide adhesive tapes with low electrostatic and flame-retardant properties can also be provided according to the special process requirements.

It can be used for high-temperature surface reinforcement and protection, surface protection of metal materials for high-temperature spraying and sandblasting coating. After high-temperature painting and baking, it can be easily peeled off without leaving any residue. It has the advantages of high temperature resistance, high tensile strength, good chemical resistance, and no residue, and is compliant with RoHS environmental protection and halogen-free.

Polyimide adhesive tapes are trustworthy materials that can be well applied in high-tech products because they can perform their functions well within the applicable range, and sometimes can even work normally under ultra-high temperature conditions. These are the many advantages of polyimide adhesive tape.
