Perfluoroalkoxy resin chemical resistance

PEA are fully fluorinated and melt processible [70,72,93]. They have chemical resistance and thermal stability comparable to those of PTFE. The specific gravity of perfluoroalkoxy resins is in the range of 2.12-2.17 and PFA has an upper continuous use temperature of 260°C. [Pg.64]

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]
