Expansion tape

· Product description:

Substrate: Synthetic resin
Adhesive: Polyacrylate
Color: white transparent
Specifications:(980mm) width (100M, 200M, 300M) length

· Product characteristics:

Using synthetic resin as the base material, the expansion rate is high and the adhesion is strong. The adhesive tape of the battery core will expand after the liquid is injected into the shell, which reduces the movable space inside the battery core, effectively improves the passing rate of roller test and drop test, increases the stability of the battery, and can meet the requirements of fully automated production.

· Product Application:

Especially suitable for cylindrical lithium battery diaphragm winding fixed, can replace the traditional termination tape.
