FLONFILM™ 500

About FEP Film

FEP film (FLONFILM™ 500) is melt extruded from Fluorinated Ethylene Propylene (FEP) and enjoys excellent chemical resistance and exceptional thermal performance.

Polyflon offers two grades of FEP film:

FEP Film Type A:

Our general purpose grade is suitable for applications where chemical resistance and high temperature are a concern. Type A performs well as a non-permeable barrier to aggressive fluids in tank lining applications and fuel cell/battery assemblies. The good weatherability and optical properties of FEP film provide excellent performance in PV modules and large scale algal growth cells. Due to the ease with which Type A can be welded to itself, gas sampling bags are an effective end use.

FEP Film Type B:

Our premium grade is a translucent version produced from high molecular weight resin for applications where high flex life and stress-crack resistance are required, typical products being thin film diaphragms. The high molecular weight of Type B also affords this grade of FEP film very low gas diffusion through its wall and also exhibits an extremely smooth, self-cleaning surface finish.
