Characteristics of PP/PE/PP three-layer separator film:
Manufactured using dry stretching process
Excellent resistance to acid, alkali, and most chemicals
Uniform pore structure, with high chemical and thermal stability
Zero shrinkage in the transverse direction (TD), reducing internal short circuits and improving high-temperature dimensional integrity
Antioxidant PP outer layer ensures excellent cycling and trickle charging performance
PE inner layer provides high-speed shutdown capability
