Swelling tape

· Product description:

Substrate: Synthetic resin
Adhesive: Polyacrylate
Color: White
Specifications:(520mm) width (300M, 400M) length

· Product characteristics:

Using special synthetic copolymer as the base material and coating special polyacrylate adhesive, the product has excellent softness and conformability. After contacting with electrolyte, three-dimensional expansion effect will occur, filling the gap between the battery core and the shell, helping the battery to pass rigorous roller test in semi-electric or low-electric state, increasing the safety and stability of the battery, customizable numbers and product colors, 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.
