Abstract (en)
[origin: WO2007056350A1] A composition having excellent resistance to chemical permeation, comprising (A) a tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer, (B) a melt-flowable polytetrafluoroethylene directly obtained by the polymerization of tetrafluoroethylene, and (C) a polytetrafluoroethylene with a low molecular weight obtained by the radiolysis of a non-melt flowable polytetrafluoroethylene with a high molecular weight; the weight ratio of A/(B + C) is 80/20 to 30/70; and the weight ratio of (A + B)/C is 99.99/0.01 to 90/10.
