摘要:
A thermoprocessable copolymer of TFE essentially formed by: (a) from 4.5 to 8.5% by weight of perfluoromethylvinylether (PMVE); (b) from 0.3 to 1.6% by weight of a perfluorodioxole of formula: wherein: Y=F, ORf, Rf wherein Rf is a perfluoroalkyl having from 1 to 5 carbon atoms; X1 and X2, equal to or diferent from each other, are —F or —CF3; (c) TFE, forming the remaining part to 100%.
