Execution standard: Q/DYS 003-2007
Fluorinated ethylene-propylene (FEP) resin, as a copolymer of tetrafluoroethylene and hexafluoropropylene, has good heat stability, outstanding chemical inertness, excellent electrical insulation and low friction coefficient, and can be processed by a thermoplastic processing method.
Translucent particle, scrap metal, sand and other impurities cannot be mixed, particles with visible dark spots cannot exceed 6%

Hot stress crack resistance
The extruded plastic resisting hot stress crack is mainly used for wire insulating layers and thin walled pipes.
Avoid processing at above 420℃ to prevent decomposing and generating toxic gas.
Packaging, Transport and Storage:
1. It should be packaged in two-layer plastic inner bag, and then sealed in hard drum. Each bag has net weight of 25kg and certificate of approval.
2. It should be stored in a clean, dry, cool and shady environment to prevent mixing of impurities.
3. It is nontoxic, non-inflammable, nonexplosive and noncorrosive, so it is transported according to non-dangerous goods.
