Swelling tape

· Product description:

Substrate: Synthetic resin
Adhesive: Polyacrylate
Color: White
Specifications:(520mm) width (200M, 300M) length

· Product characteristics:

Using a special synthetic copolymer as the base material and coating a special polyacrylate adhesive, the product has excellent softness and conformability, and will undergo a three-dimensional expansion effect after contact with electrolyte, filling the gap between the battery core and the shell, helping the battery to pass rigorous roller tests under semi-electric or low-electric conditions, increasing the safety and stability of the battery, and meeting the requirements of fully automated production.

· Product Application:

Especially suitable for high quality cylindrical lithium ion battery separator winding parts of the winding adhesive.
