FEP Specification
FEP Specification
Description:
FEP granule is copolymer of tetrafluorothylene(TFE) and hexafluoropropylene(HFP) with excellent thermo-stability, outstanding chemical interness, low friction coefficient, distinctive air aging resistance, vapor penetrating resistance, non-inflammability and superior electrical insulation.

Application:
FEP-1 : It’s used as insulation for small-gauge high temperature wire or jacketing for smallgauge data andtelecommunications cables
FEP-2：It’s used as insulation or jacketing for high temperature wire & mostgauge data and telecommunicationscables, corrosive-resistent tube or pipe.
FEP-3：It is mainly used for insulation and sheath of high-temperature wire and cable. It can also be used for largespecification data, sheath of communication wire, insulation, pipe and film resistant to high temperature andcorrosion.
FEP-4：It’s be widely used as liner for valve, pump and tube.
Physical and chemical properties:
The molecular weight of FEP is 200000-600000, MFR (372 ℃, 5kg) is 0.8-32g/10min, melting point is 250-275 ℃. FEP has excellent mechanical and electrical properties. The oxygen content required for continuous combustion is 95 vol%, and it has good chemical resistance.
Storage & transportation:
The product should be stored in a clean, cool and dry place to prevent rain, sun, moisture, dust and other impurities from mixing.
Packing specification：
packed in PE plastic bag then put in hard carton barrel, Net weight of each package is (25±0.2)kg.
