Ultra high molecular weight polyethylene separator (hereinafter referred to as the pe separator) is a kind of micro porous membrane that uses polyethylene as base material and silica as filler material. It is mainly used for lead-acid batteries, separating positive and negative plates.
Compared with other types of Separators, PE separator has the characteristics of smaller pore size, easy mechanical assembly. PE separator can reduce the battery short circuit problems, improve the capacity, improve the cycle life, improve the assembly efficiency of the battery, and reduce the rejection rate and so on.
PE separator is mainly composed of silica, ultra high molecular weight polyethylene, special oil and other additives.
