FEP Extrusion Grade
FEP Extrusion GradeFEP is the copolymer of tetrafluoroethylene(TFE) and hexafluoropropylene(HFP). It has excellent thermo-stability, outstanding chemical inertness, low friction 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 transportationFEP resin is sealed in plastic bag with 25kg net weight per bag, and then packed in drum or big cardboard box. It should be stored in clean and dry warehouses to avoid pollution from impurities. The processing temperature should be below 400 ℃ to avoid releasing toxic gases.
