Abstract
A thermoplastic elastomer composition for overmolding a plastic article or 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 blend of hydrogenated styrene block copolymers and unsaturated styrene block copolymer. The method for the preparation of the overmolded article comprises applying a thermoplastic elastomer composition to at least a portion of the exterior surface of a rigid plastic substrate.
Claims33

- a second hydrogenated styrene block copolymer having a second styrene content that is less than the first styrene content of the first hydrogenated styrene block copolymer;
- an unhydrogenated styrene block copolymer;
- and
- a plasticizer.
