ACCOPPIATI DI FLUOROPOLIMERI CON POLIVINILCLORURO CLORURATO

摘要

Multilayers comprising at least one laminate formed in sequence by the following layers: A) one thermoprocessable fluoropolymer layer comprising units deriving from vinylidenfluoride (VDF); B) one polyamide layer blended with 0.01%-5% by weight of a diamine or one polyamide layer having at least 20 mu eq/g of -NH2 groups, or one thermoprocessable polymer layer containing (-COO-) units and/or -CN groups; and C) one layer based on chlorinated polyvinylchloride (CPVC) containing from 58% to 75% by weight of chlorine.
