ChemFilm® FEP Film

teflon fep roll

 

ChemFilm® FEP fluoropolymer film is manufactured by Saint Gobain Performance Plastics from fluorinated ethylene propylene (FEP) resin.

FEP also provides the chemical and thermal resistance to withstand aggressive environments, making it an excellent candidate for diaphragms, gaskets, protective linings, sample bags, and containers. Fabricated shapes and contours can be produced via heat sealing and thermoforming. The outstanding weatherability and optical properties of FEP film provide excellent performance in environmental growth chambers and solar collectors.

ChemFilm® FEP Type FG

This film grade utilizes the low dielectric constant and dissipation over a wide range of temperatures and frequencies for low-signal distortion and attenuation in flexible printed circuit and flat cable applications. The high surface and volume resistivity minimizes current leakage and provides excellent insulation in wire and cable applications.

ChemFilm® FEP Type FS

FS grade film is a translucent film made from high molecular weight resin for applications where high flex life, stress-crack-resistant, and heat seal performance are required. These applications include items such as tank linings and diaphragms.

ChemFilm® FEP Type WF

Type WF (mechanical grade) film is an ideal economical solution for applications that don’t require high aesthetic standards, such as hot melt adhesive (welding tape) application. FEP WF film possesses all physical, mechanical, and thermal properties of FEP FG grade, while offering up to 15% savings.
