Norton® FEP fluoropolymer film is manufactured from fluorinated ethylene propylene (FEP) resin by Saint-Gobain Films in four grades.
Norton® 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.
Norton 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 Norton FEP film provide excellent performance in environmental growth chambers and solar collectors.
Norton® FEP Type FS
FS grade film is a translucent film made frm high molecular weight resin for applications where high flex life and stress-crack-resistant performance are required, such as tank linings and diaphragms.
Norton® FEP Type RF
Type RF film is a clear or pigmented film designed for release applications. The non-stick surface, chemical resistance, and 205°C (400°F) usage temperature make Norton FEP an ideal release film for comosite molding over a wide range of resin systems. High elongation and a smooth, low-gel film surface allow Norton FEP to conform to complex mold contours and produce a smooth part finish. Perforated film is available to control outgassing and resin bleed. Pigmented films increase visibility to speed removal from parts and mold.
Norton® 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.
