Glass run channel

A glass run channel comprising:

• a glass run channel body, said glass run channel body comprising a bottom wall and side walls extending from two opposite edges of the bottom wall, said glass run channel body having a substantially U-shaped section and provided with a groove, and
• tongue-shaped draining parts protruding from vicinities of distal edges of the side walls toward the bottom wall of the glass run channel body so as to become proximate to each other, said tongue-shaped draining parts each having a window glass contact part composed of a surface to be brought into contact with a window glass,
• wherein said window glass contact part comprises a layer of a thermoplastic elastomer (A) composed of a crystalline polyolefin and a rubber and a layer of an ultrahigh molecular weight polyolefin composition (B),
• said layer of ultrahigh molecular weight polyolefin composition (B) arranged so as to contact with a window glass,
• said ultrahigh molecular weight polyolefin composition (B) comprising:
• 10 to 90 parts by weight of a polyolefin composition (a') having an intrinsic viscosity (.eta.) of 3.5 to 8.3 dl/g as measured in a solvent of 135.degree. C. decalin, said polyolefin composition (a') consisting essentially of:
• an ultrahigh molecular weight polyolefin (a-1) having an intrinsic viscosity (.eta.) of 7 to 40 dl/g as measured in a solvent of 135.degree. C. decalin, and
• a polyolefin (a-2) having an intrinsic viscosity (.eta.) of 0.1 to 5 dl/g as measured in a solvent of 135.degree. C. decalin,
• said ultrahigh molecular weight polyolefin (a-1) being present in an amount of 15 to 40% by weight based on the sum of ultrahigh molecular weight polyolefin (a-1) and polyolefin (a-2), and
• 10to 90 parts by weight of an olefinic thermoplastic elastomer (b) composed of a crystalline olefinic resin and an olefinic rubber, provided that the sum of component (a') and component (b) is 100 parts by weight.
