US 2021/0198464 A1 · THERMOPLASTIC ELASTOMER COMPOSITION FOR OVERMOLDING POLYAMIDES

Abstract

A thermoplastic elastomer composition for overmolding a predominantly polyamide substrate, a method for the preparation of an overmolded article, and an overmolded article having a layer of thermoplastic elastomer is provided. The thermoplastic elastomer composition comprises a thermoplastic vulcanizate, an olefinic block copolymer, and a maleated functionalized polyolefin copolymer. The method for the preparation of the overmolded article comprises heating the thermoplastic elastomer composition followed by applying the heated composition to at least a portion of the predominantly polyamide substrate.
