Patent ID: 7811653

Claim:
An extrusion molded article for automobiles, having a body portion and a hollow sealing portion, where the body portion comprises a core made of a resin having a U-shaped cross-section extending in a longitudinal direction and a covering layer surrounding and covering the core partly or entirely, and the hollow sealing portion is bonded integrally with an outer surface of the body portion, characterized in that the covering layer is made of a thermoplastic elastomer composition having a tensile elongation at break of at least 350%, as determined according to the Japanese Industrial Standards (JIS) K6251, and a change in 100% modulus of at most 40%, wherein the change in 100% modulus=[(100% modulus at 23° C.-100% modulus at 80° C.)/100% modulus at 23° C.]×100, and the 100% modulus is a stress at 100% elongation, as determined according to JIS K6251, the hollow sealing portion is made of a thermoplastic elastomer composition having a tensile elongation at break of at least 250%, as determined according to JIS K6251, and a compression set of 35% or less, as determined at 25% compression, 70° C., 200 hours, the thermoplastic elastomer composition forming the covering layer comprises a crystalline olefin resin in an amount of 27.5 to 63 parts by weight of the composition, and the thermoplastic elastomer composition forming the hollow sealing portion comprises a crystalline olefin resin in an amount of 4 to 22 parts by weight of the composition.
