Method : ASTM D1434 for gases. It is often used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required. To clarify the correlation between surface potential and contact electrification, the materials before and after modification were contacted-separated with a fluorinated ethylene propylene (FEP) copolymer film for 10 min, and then changes in the surface potential were evaluated. FEP extrusionsFluorinated ethylene propylene (FEP) and tetrafluoroethylene–perfluoro(alkoxy vinyl ether) (PFA) copolymer films were irradiated in vacuum with 60 keV C 4+ and N 4+ ions to fluences ranging from 1. 125 mm, L 0. ΔL is the change in length of test specimen due to heating or to cooling. Although it is lower melting than PTFE, it still maintains a continuous. 1-99. Three-layer piezoelectrets from fluorinated ethylene-propylene (FEP) copolymer films. It is a copolymer made from 2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole (PPD) and TFE.
