Abstract
Abstract An abrasion-resistant fluoropolymer mixture comprising (A) from 75 to 99% by weight of a fluorocarbon polymer (B) from 1 to 25% by weight of an oxidized polyarylene sulfide and, based on the sum (A)+(B), (C) from 0 to 15% by weight of a filler, is used for the production of feed pipes for Bowden cables which are pressure-resistant and abrasion-resistant.
