FLONFILM™ 500 FEP Film

FLONFILM™ 500 FEP Film

 

(Fluorinated Ethylene Propylene)

FLONFILM™ 500 FEP film is melt extruded from fluorinated ethylene propylene; 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.

 

Key Features of FEP Film:

  • Excellent electrical insulator.
  • Very low coefficient of friction – excellent release.
  • High degree of transparency.
  • No voids or pinholes – low permeability.
  • Excellent chemical resistance.
  • Temperature range of -254°C to +200°C (-425°F to 390°F).

Availability of FEP Film:

Polyflon can offer FEP film in semi-finished form on standard rolls or converted into finish cut/thermoformed/punched parts.
