Neoflon PFA Melt Resins
Perfluoro Alkoxy Fluoropolymers
Daikin PFA (Perfluoro Alkoxy) is a copolymer of TFE and perfluoroalkyl vinyl ether. Like PTFE and FEP, it is fully fluorinated. Like FEP, it is melt processible. PFA has a continuous service temperature from -200 Deg C to +260 Deg C. Like PTFE, PFA has extreme chemical inertness, excellent slip and release properties, and excellent electrical properties. PFA also has excellent high temperature mechanical properties. Daikin produces two types of PFA, industrial grades and semicondutor or “SH” grades. Both types can be easily processed by extrusion, compression molding, injection molding, transfer molding, or other typical plastics processing methods. Semiconductor grades have the additional benefit of being extremely low in metal and fluoride ion extractions, meeting all semiconductor requirements for ultrapure chemical tubing and associated equipment. Typical applications are injection molded parts, medical devices, extruded wire insulation, tubing, film and sheet lining. Anti-static industrial grades are also available.
