产品描述

Composite Separator Series (Glass Fiber) PVC Separator

Composite separators are receiving increasing attention from battery manufacturers because the glass fiber coating effectively prevents the active material on the plates from falling off and causing short circuits.

PVC battery separators are mainly used in traction batteries and also in some industrial batteries, such as straight-ribbed and oblique-ribbed separators. Their good strength and ease of assembly for workers have given PVC separators a considerable market share.
