FEP-FS High Molecular Weight Film
CHEMFILM® FEP-FS film is made from high molecular weight fluorinated ethylene propylene resin for applications where high flex life and stress-crack-resistant performance are required, such as tank linings and diaphragms. It temperature performance range and resistance to chemical attack make it an ideal candidate for chemical processing. The film meets or exceeds the requirements of ASTM D-3368 (Specification for FEP-Fluorocarbon Resin Sheet and Film) for type III material.
