FEP has very similar properties to PFA and in some cases can be a direct alternative. Fluon® PFA. Typical process heating systems are designed to maintain at least 400°C. For various chemical compounds and alloys, it is difficult to define the melting point, since they are usually a mixture of various chemical elements. Combining the best of PTFE and FEP, PFA was developed in the late 1960's in response to a need for a resin with chemical and use temperatures closer to PTFE, yet a resin that would retain the conventional melt processability of FEP. The porous material is composed of a polytetrafluoroethylene and a heat-meltable resin of which melting point is lower than that of the. The increases in enthalpy and volume at the melting point both indicate a degree of crystallinity of about 75–80% although infrared, x-ray, and NMR data give much higher levels. 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.

It offers low friction and chemical inertness properties comparable to PTFE’s. Melting point °C (°F) 171 – 175 34( 0 – 347) 158 – 166 to process, however, because of its high melting temperature (343 °C / 649 °F). Advertisement. In addition, it possesses good radiation resistance, which makes it ideal for high-end applications in the semiconductor, pharmaceutical, life science, and photovoltaic industries. We do not guarantee the safety in case the. Fluon ® PFA (or perfluoroalkoxy) is a fluoropolymer with excellent thermal and chemical resistance.
