Fluoroplastics are a class of paraffinic polymers that have some or all of the hydrogen replaced by fluorine. These include polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP) copolymer, perfluoroalkoxy (PFA) resin, polychlorotrifluoroethylene (PCTFE), ethylene-chlorotrifluoro-ethylene (ECTFE) copolymer, ethylene-tetrafluoroethylene (ETFE) copolymer, polyvinylidene fluoride (PVDF), and polyvinylfluoride (PVF) [186],...

Perfluoroalkoxy (PFA) fluorocarbon resins are designed to meet industry s needs in chemical, electrical, and mechanical applications. These melt-processible copolymers contain a fluorocarbon backbone in the main chain and randomly distributed perfluorinated ether side chains ... [Pg.5468]

Perfluoroalkoxy Resin (PFA) A class of melt-process-able fluoroplastics in which perfluoroalkyl side chains are connected to the fluorocarbon backbone of the polymer through flexible oxygen linkages. PFA resins have the desirable properties associated with fluoroplastics plus superior creep resistance, and are more easily processed by extrusion and injection molding. [Pg.526]

PFA polymers are fully fluorinated and melt processible. They have chemical resistance and thermal stability comparable to polytetrafluoroethylene (PTFE). Melt viscosity of PFA is over one million times lower than PTFE. Perfluoroalkoxy resins are in general copolymers of tetrafiuoroethylene with one or more of perfluoroalkyl vinyl ether comonomers. Commercial examples of the latter include perfluoromethyl vinyl ether (PMVE), perfluoroethyl vinyl ether (PEVE), and perfluoropropyl vinyl ether (PPVE). PFA resins are specified by ASTM Method D3307, which also provides procedures or references to other ASTM methods for the measurement of resin properties. Commercial PFA resins offered by major manufacturers have been listed in Tables 6.1 through 6.7. [Pg.123]

Perfluoroalkoxy resin (PFA) is a copolymer of TFE and perflnoropropy-1 vinyl ether (PPVE) in a mole ratio of approximately 100 1. Even snch a small amonnt of comonomer is snflicient to prodnce a copolymer with a greatly rednced crystallinity. The relatively long side chains also markedly rednce the cold flow. Methylflnoroalkoxy resin (MFA), a copolymer of TFE and perfln-oromethylvinyl ether (PMVE), has similar properties with a somewhat lower melting point. [Pg.31]

Perfluoroalkoxy resin (PFA) Copolymer of tetrafluoroethylene (TFE) with perfluoro(propylvinyl ether), an engineering thermoplastic characterized by excellent thermal stability, release properties, low friction and toughness. Its performance is comparable to poiytetrafluoroethylene (PTFE) with the difference that it is melt processible. [Pg.201]
