FEP Resin for Extrusion
FEP is the copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). It has excellent thermo-stability, outstanding chemical inertness, lowfriction coefficient, distinctive air aging resistance, vapor penetrating resistance, non-inflammability and superior electrical insulation.
FEP extrusion grade is mainly used in extruding insulation layers and jackets for conducting wire and cable. It’s also widely used in the production of pipe, tube, film and etc.

Package, storage and transportation:
FEP resin issealed in plastic bag with 25kgnet weight per bag, and then packed in drum or big cardboard box. It should bestored in clean and dry warehouses to avoid pollution from impurities. The processing temperature should be below 400℃to avoid releasing toxic gases.
