This tape is made of OPS heat-shrinkable film coated with proprietary electrolyte-resistant acrylic pressure-sensitive adhesive. It is specially applied in the post-filling process of cylindrical power cells. After electrolyte injection, the tape swells tightly to bond bare cells and steel shells together, enhancing the overall impact resistance of batteries.

Customizable length: 0 ~ 200m.

Customizable thickness: 44 ~ 54um.

85℃/4h in electrolyte, no residue.

High expansion ratio, thickness expansion ratio up to 300% after injection.
