Positive high temperature tape

· Product description:

Substrate: Polyimide film
Rubber system: rubber
Color: Coffee
Specifications:(13mm) width (460M) length

· Product characteristics:

Using a substrate with good thermal stability and a high-performance pressure-sensitive adhesive, it has good temperature resistance and is well attached to the substrate after peeling at 100 ℃/4h. In the electrolyte, it has the characteristics of good swelling resistance, precipitation resistance, stable adhesive layer state and stable peeling force. Immersed in the electrolyte at 85 ℃/50d, it still stably adheres to the pole piece, has stable electrochemical cycle voltage, and solves the problem of tape blackening after cyclic charging and discharging. Effectively solve the problem of reduced battery life and short-circuit of the battery caused by carbonization and precipitation of the tape after cycle charging and discharging.

· Product Application:

Suitable for all kinds of steel shell, aluminum shell, soft package, polymer battery core pole piece part of the adhesive protection.

Technical parameters:
