The Introduction of FEP Resin Thermoplastic process DS601

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
