An automobile weatherstripping includes an extrusion-formed part and a mold-formed part, the mold-formed part being welded and integrated with the extrusion-formed part. The extrusion-formed part is made of an olefin elastomer and the mold-formed part is made of a resin composition containing an olefin resin, ethylene-.alpha.-olefin copolymer rubber, hydrogenated aromatic vinyl conjugated diene compounds block copolymer mineral oil and at least one of natural rubber and butadiene rubber in predetermined proportions. The extrusion-formed part and the mold-formed part have a sufficient level of bonding strength with no bonding agent layer being used therebetween.
A door weather strip having an extruded member and a molded corner for connecting ends of the extruded member. The extruded member is composed of a foamed thermoplastic olefin elastomer which has an average cell diameter of 30 to 70 .mu.m and an expansion ratio of 150 to 250%.
The foamed laminate based on olefin according to the present invention is composed of a substrate layer of a foamed body made of either an ethylenic thermoplastic elastomer comprising a polyethylene resin and an ethylene/.alpha.-olefin copolymer having a Mooney viscosity ML.sub.1+4 (100.degree. C.) of 90-250 and an ethylene content of 70-95 mole % or an ethylenic thermoplastic elastomer composition comprising 100 parts by weight of an olefinic thermoplastic elastomer and 1-20 parts by weight of an olefinic thermoplastic resin and, under lamination thereon, a skin layer made of either an ultrahigh molecular weight polyolefin resin having an intrinsic viscosity of 3.5-8.3 dl/g or made of an olefinic thermoplastic elastomer composition comprising an olefinic thermoplastic elastomer and a lubricant. The foamed laminate according to the present invention is easy in recycled use, obtainable at a high foaming expansion ratio with soft hand touch and is superior in the appearance, abrasion resistance, durability and sliding performance.
