Product Description

Battery Separator Celgard 2325/2320/2340 is Microporous Trilayer Membrane(PP/PE/PP)

product Advantage

Polypropylene PP Battery Separator Film Celgard 2400/2500 for Lithium-ion Cell Lab Research

●Excellent resistance to acids, alkalis and most chemicals.

● Consistent pore structure with high chemical and thermal stability

● Oxidation resistance for excellent cycling&trickle charge performance.

● Antioxidant PP outer layer ensures excellent cycling and trickle charge performance.

● PE inner layer provides high-speed shutdown.

● Transverse (TD) zero shrinkage reduces internal shorts and improves high temperature scaleinch integrity.

Product Features:

● Zero TD shrinkage reduces internal shorting

● Uniform pore structure with high chemical & thermal stability

● Medium porosity provides excellent energy performance

● PP layer provides superior high temperature melt integrity compared to other polyolefin-based, uncoated separators as well as oxidation resistance

● Offers exceptional safety and longevity for energy applications
