Polyimide rubber tape offers excellent heat resistance, strong adhesion, and reliable electrical insulation. Ideal for coil wrapping, motor insulation, wave soldering masking, and high-temperature bonding in electronics and automotive applications.
Polyimide film as base film,using a substrate with good thermal stability and high-performance pressure-sensitive adhesive, it has good temperature resistance and can peel off and adhere well to the substrate after 100 ℃/4h; In the electrolyte, it has the characteristics of good swelling resistance, precipitation resistance, stable adhesive layer state, and stable peeling force. Even after soaking in the electrolyte at 85 ℃/50d, the electrode still adheres stably, the electrochemical cycling voltage is stable, and the problem of tape blackening after cyclic charging and discharging is solved. Effectively solve the problems of reduced battery life and short circuit caused by carbonization and precipitation of adhesive tape after cyclic charging and discharging.
