Description
Sida Lithium Battery Expansion Tape is designed to expand after contact with electrolyte, helping fill gaps between the cell and housing. The tape uses OPS backing with acrylic adhesive, 0.041+/-0.005mm total thickness, and 100m roll length. It supports more than 200% expansion after room-temperature electrolyte exposure for 12 hours or 85C exposure for 2 hours.
