Fluon® PFA (or perfluoroalkoxy) is a fluoropolymer with excellent thermal and chemical resistance.
Fluon® PFA is similar in composition to the fluoropolymers PTFE and FEP (fluorinated ethylene propylene), sharing low coefficient of friction, non-stick properties and non-reactivity characteristics. Fluon® PFA resists UV light and has better heat resistance, higher melt strength and can be used within a temperature range of -200ºC to 260ºC.
Fluon® PFA also offers stability at high processing temperatures, excellent crack and stress resistance whilst maintaining more than ten times the flex life of FEP. A low dielectric constant allows Fluon® PFA to be used in semiconductor manufacturing and many electrical applications. Fluon® PFA coating is ideal when extended services are required in hostile environments including chemical, thermal and mechanical stress.
As with other thermoplastic resins Fluon® PFA can be extruded, injection moulded, blow moulded and transfer moulded for applications such as tubing, receptacles, lining and wire coating.
