This lower melting point made FEP the first melt-processable perfluorinated polymer. Melting temperature of 2 mil thick PET film was 255 –PFA was found to improve the gas barrier properties of PCL without compromising its mechanical properties, and it demonstrated sustained antioxidant effect with excellent biocompatibility. It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (−268. 45 MPa) ASTM D648 — @ 264 psi (1. 폴리 불화 비닐 리덴 (PVDF) 폴리 염화 비닐 (PVF) FEP 인 F46 은 테트라 플루오로 에틸렌과 헥사 플루오로 프로필렌의 공중 합체입니다. 4 a–d).
