Poreflon® Membrane


Poreflon Membrane are PTFE (poly terafluoroethylene)porous membranes produced by our unique expansion-technology. It features chemical resistance,heat resistance,high retention of very small particles and high flow capability.

In addition, we can make the water-repellency surface of the PTFE (Polytetrafluoroethylene) hydrophilic by original processing technique . Poreflon™ hydrophilic membrane is most suitable for the filtration of the water solution.
Poreflon™ Membrane is superior in weather resistance, a low dielectric characteristic like water-repellency. It is utilized as a waterproofing film for electronic parts in the field of car and the household electrical appliance etc, as a covering material of the electric wire.
