Patent ID: 6866939

Claim:
A glass-run channel comprising: (i) a surface layer comprising a polyolefinic thermoplastic elastomer (A) manufactured by dynamically heat treating, in the presence of a crosslinking agent, 10 to 60 wt. parts of a polyolefin resin (X), 30 to 70 wt. parts of a rubber component (Y) comprising at least an ethylene-α-olefin-non-conjugated polyene copolymer rubber and 5 to 50 wt. parts of an oily softening agent (Z), the total of (X), (Y) and (Z) being 100 wt. parts, and (ii) an underlayer comprising a polyolefinic thermoplastic elastomer (B) manufactured by dynamically heat treating, in the presence of a crosslinking agent, 10 to 60 wt. parts of a polyolefin resin (X′), 30 to 70 wt. parts of a rubber component (Y′) comprising at least an ethylene-α-olefin-non-conjugated polyene copolymer rubber and 5 to 50 wt. parts of an oily softening agent (Z′), the total of (X′), (Y′) and (Z′) being 100 wt. parts, which underlayer is laminated on the surface layer, wherein the ratio (a) of the oily softening agent (Z) to the total of the rubber component (Y) and the oily softening agent (Z), or if polyethylene is incorporated, to the total of the rubber component (Y), the oily softening agent (Z) and polyethylene in said thermoplastic elastomer (A) and the ratio (b) of the oily softening agent (Z′) to the total of the rubber component (Y′) and the oily softening agent (Z′), or if polyethylene is incorporated, to the total of the rubber component (Y′), the oily softening agent (Z′) and polyethylene in said thermoplastic elastomer (B) satisfy the following requisite; ratio (a)≧ratio (b).
