Dry-Process PP Battery Separator Film 16μm / 20μm / 25μm

Quick Answer

Dry-process PP separator film is a porous polypropylene membrane used to physically separate positive and negative electrodes while allowing ionic transport through the electrolyte in battery cells. This product is available in 16μm, 20μm, and 25μm thicknesses with a standard width of 60mm.

Description

Dry-process polypropylene (PP) separator film is designed for laboratory battery research and cell assembly. The porous PP membrane provides physical separation between the positive and negative electrodes while maintaining the ion-transport pathway required for electrochemical operation.

Three thickness options are available: 16μm, 20μm, and 25μm, all supplied at a standard width of 60mm. The different grades provide different basis weights, porosities, air permeability values, mechanical strengths, and puncture resistance, allowing researchers to select the separator according to their experimental requirements.

Standard roll lengths include 10m, 20m, and 100m.
