Fluorinated ethylene propylene or FEP Sheet is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the PTFE (polytetrafluoroethylene) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful properties of low friction and non-reactivity, but are more easily formable. FEP is softer than PTFE and melts at 260 °C; it is highly transparent and resistant to sunlight.

Remark:
1. Tolerance is according to DIN Length: 0~3 %, width: 0~ 3%.
2. it is theoretical value for above spec, Films with 300 x 300mm and sheets with the 1000 x 1000 mm
3. Taking objective as standard, listed data are for reference only.
4. The products above have been strictly treated with tempering; the strain value has met the minimum.
