Separator Celgard 2340 is composed of PP/PE/PP three-layer diaphragm, which is produced by dry stretching manufacturing process; Excellent resistance to acids, alkalis and most chemicals; consistent pore structure with high chemical and thermal stability; Transverse (TD) zero shrinkage reduces internal shorts and improves high temperature scaleinch integrity;
Antioxidant PP outer layer ensures excellent cycling and trickle charge performance PE inner layer provides high-speed closing capability.
