摘要： Polyoxymethylene with improved resistance to acids, comprising A from 84 to 99.79% by weight of at least one polyoxymethylene homo- or copolymer, B from 0.1 to 5% by weight of at least one polyalkylene glycol, C from 0.1 to 10% by weight of zinc oxide, and D from 0.01 to 1% by weight of one or more nitrogen-containing costabilizers, where the total of the percentages by weight of components A to D is 100%. This polyoxymethylene is particularly advantageous when used for producing moldings for use in contact with aggressive acids or with aggressive acid-containing cleaning agents, in particular for applications in the sanitary sector or the white goods sector.

摘要： It has been found that, in particular, a molding composition comprising (A) from 80 to 99.8% by weight of a polyoxymethylene homopolymer or copolymer, (B) from 0.1 to 10% by weight of a polyalkylene glycol and (C) from 0.1 to 10% by weight of a zinc oxide, where the sum of the percentages by weight of components (A) to (C) in each case gives 100%, is suitable for the production of moldings for applications with direct contact with diesel fuel or gasoline. Moldings produced therefrom satisfy the increased demands regarding resistance to aged fuels, diesel fuel at high long-term service temperatures and aggressive gasoline.
