Patent ID: 7150919

Claim:
An article of manufacture that is comprised of a soft thermoplastic elastomer composition overmolded onto a hard substrate wherein the soft thermoplastic composition is comprised of (a) a thermoplastic resin selected from the group consisting of polyolefin resins, polyphenylene ether, and polystyrene, wherein the thermoplastic resin is present at a level of up to 60 parts by weight (b) 5 to 90 parts by weight of a rubbery elastomer that is comprised of repeat units that are derived from a conjugated diene monomer selected from 1,3-butadiene and isoprene, wherein the rubbery elastomer is optionally at least partially crosslinked, wherein the repeat units in the rubbery polymer are distributed throughout the rubbery polymer in an essentially random manner, and wherein the rubbery polymer is a solution polymer, (c) 5 to 90 parts by weight of a highly saturated elastomer selected from the group consisting of styrene-ethylene butylene-styrene polymers, styrene-ethylene propylene-styrene polymers, hydrogenated polybutadiene, hydrogenated polyisoprene, hydrogenated styrene-isoprene random copolymers, hydrogenated styrene-isoprene block copolymers, hydrogenated styrene-butadiene random copolymers, hydrogenated styrene-butadiene block copolymers, and (d) 15 to 600 parts by weight of an oil.
