ABSTRACT:
Composite bodies, processes for making them, and their uses are disclosed, the composite bodies comprising a polyacetal portion and a modified thermoplastic vulcanizate portion bonded together, wherein the modified thermoplastic vulcanizate portion comprises a modified thermoplastic vulcanizate elastomer having a hardness of 30 to 90 Shore A and wherein the modified thermoplastic vulcanizate elastomer comprises: (a) 2 to 75% by weight of an at least partially crosslinked ethylene-propylene-diene rubber in from 1 to 50% by weight of a polyolefinic matrix further comprising 0.05 to 10% by weight of an ingredient selected from the group consisting of stabilizers, crosslinking aids, and mixtures thereof; (b) 1 to 30% by weight of a compatibilizer; and (c) 10 to 70% by weight of a non-olefinic thermoplastic material, all percentages by weight based on a total weight of the modified thermoplastic vulcanizate elastomer.
