ABSTRACT:
Methods for forming a composite for use as a vehicle weather strip and the products formed thereby are disclosed in which a main body member is formed from an elastomer polymer and an abrasion resistant decorative layer including a blend of a crosslinkable thermoplastic polyolefin and a thermoplastic vulcanizate is applied thereon. The crosslinkable thermoplastic polyolefin preferably includes a crosslinkable olefin homopolymer. The olefin homopolymer preferably contains grafted silane functional groups to allow the material to be crosslinked in the presence of moisture. The abrasion resistant decorative layer may be extruded or otherwise applied onto the main body either prior to or after the main body member is cured and either prior to or after the crosslinkable polyolefin of the abrasion resistant decorative layer is crosslinked. The material of the abrasion resistant decorative layer may be extruded into sheet form and laminated onto the main body member.
