Abstract

The invention relates to an extrusion molded product having a core material. An anti-skid thermoplastic elastomer composition forms a contact portion on a part of a surface of retaining portion, and then the situation that oil moves and attaches to a surface of the contact portion can be prevented. The thermoplastic elastomer composition forming the contact portion (6) includes, by weight, 30-60 parts of component (a) which mainly includes segmented copolymer of at least two polymer blocks A of vinyl aromatic compounds and at least one polymer block B of conjugated diene compounds, and / or hydrogenated segmented copolymer acquired by hydrogenating the egmented copolymer; 10-30 parts of component (b) which is homopolymer of ethylene or propylene, or crystalline copolymer mainly including ethylene or propylene; 25-55 parts of component (c): a rubber softener, wherein (a)+(b)+(c)=100 parts; 3-15 parts of component (d): petroleum resin and / or hydrogenated petroleum resin acquired by hydrogenating the petroleum resin.

Description

technical field [0001] The present invention relates to extrusion molded products having a core material, such as weather stripping and door and window trim, for fitting them around openings in motor vehicle bodies, such as doors, trunks in the rear of automobiles, and rear doors Mounted on the surrounding flange. Background technique [0002] In an extrusion molded product having a core material for installing it around an opening of a motor vehicle body, such as a door, a trunk of a car rear, and a periphery of a rear door, the molded product main body (1) includes , a gripping portion (2) having a substantially U-shaped cross-section formed by a core material (3) and a coating element (4) of a thermoplastic elastomer composition; the gripping portion (2) has at its side portions (7) The retaining part (5) that internally forms, makes retaining part (5) protrude from coating element (4) respectively; As Figure 9 As shown, the molded product body (1) is mounted on the fla...
