PFA has more potent electrical properties than PTFE. CAS Number: 30525-89-4. 46 MPa (66 psi) 73 °C 163 °F Deflection Temperature at 1. Fluorinated Ethylene Propylene (FEP) FEP is a material type that is highly flame-resistant and commonly used in military applications. In PFA/PTFE blends, there were two melting and two crystallization peaks, originating from PTFE and PFA, except for a very rapid crystallization condition under which onlyIce (solid (ce {H_2O})) is a molecular compound whose molecules are held together by hydrogen bonds. melting point: 305°C. 06 High melting points (327°C [621°F] for PFA PTFE; 260°C [500°F] for PFA FEP, and 305°C [582°F] for PFA PFA).
