ABSTRACT:
An extrusion molded article for automobiles, having a body portion (1) and a hollow sealing portion (11), where the body portion (1) comprises a core (2) made of a resin having a U-shaped cross-section extending in a longitudinal direction and a covering layer (3) surrounding and covering the core partly or entirely, and the hollow sealing portion (11) is bonded integrally with an outer surface (4) of the body portion, characterized in that the covering layer (3) is made of a thermoplastic elastomer composition having a tensile elongation at break of at least 350%, as determined according to 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, and the hollow sealing portion (11) 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.
