Kapton tape, also known as Polyimide (PI) tape, refers to a polymer with imide groups (-CO-NR-CO-) in its main chain. Due to the presence of imide groups, thermally cured polyimide exhibits excellent heat resistance. By coating it with high-temperature pressure-sensitive adhesives such as silicone or acrylic, it can be made into a tape with outstanding high-temperature performance. It possesses excellent properties such as high and low temperature resistance, acid and alkali resistance, and solvent resistance, and maintains good performance even under extreme temperatures and vibrations, making it the optimal choice for designers. It can preserve the operational performance of machines under harsh conditions.
