The Introduction of FEP Resin Thermoplastic process DS601
FEP DS601 Processable fluoropolymer
Perfluorinated ethylene-propylene coplymer (DS601) (FEP)
Composition and structure of polyperfluoroethylene propylene (FEP Resin) Perfluorinated ethylene propylene (F46) is a copolymer of tetrafluoroethylene and hexafluoropropylene. The content of hexafluoropropylene is about 18%, and it is polytetrafluoroethylene. Modified materials of Polytetrafluoroethylene; PTFE. FEP, like PTFE, is a completely fluorinated structure, except that some of the fluorine atoms in the FEP main chain are replaced by trifluoromethyl-CF3),
as shown in Fig
The crystalline structure of FEP is between 30 and 555.The crystalline structure of FEP is not sensitive to the forming conditions, especially to the cooling rate. At the processing temperature, the real flowing melt can be obtained. Therefore, the low-temperature stable structure of its products is generally no porosity. FEP is shown in figure

Main Applications of FEP Resin Thermoplastic process DS601:
FEP Resin DS601:Hear stress cracking resistant plastics,mainly for wire insulation layer,thin-walled tube.
FEP Resin DS602: The low melting index resin and heat stress cracking resistant moulding plastic,used for stress cracking resistant requiring and low or medium speed processing,mainly for heat shrinkable tubes,pumps,valves,piping and lining,wire insulation layer.
Attention:
The processing temperature should be not exceed 420°C,to prevent toxic gas from releasing.
Package,Transportation and storage of FEP Resin Thermoplastic process DS601
Packed in double layer PVC bags,then closed to over pack bags,25kg.Every bag with certification.
Stored in clean,cool and dry places,avoid contamination form foreign substance such as dust and moisture.
Nontoxic,noninflammable,inexplosive,no corrosion,the products are transported according to non-dangerous product.
"High quality, reasonable price ,Prompt delivery and considerate service after sales" is our principle for our customers.
