Abstract: A weatherstrip assembly includes a metal surface, a thin tie layer of polymeric material covering at least select portions of the metal surface, and an elastomeric material received over the thin tie layer of polymeric material and exhibiting improved bonding with the metal through the thin layer of polymeric material. Preferably, the thin tie layer is a polypropylene-based olefinic copolymer and an ethylene acrylic acid copolymer.

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.

Abstract: A cross-linked, extruded article comprising an elastomeric base material, the surface of which is applied with a thermoset slip coat material, the article exhibiting enhanced slip and a coefficient of friction of no greater than 0.25 and process of making is provided. An extrudable, cross-linkable slip coat comprising a cross-linked thermoset polymer capable of bonding with an elastomeric base material in the absence of adhesive or binder upon contact and process of making is also provided.

Abstract: The present invention relates to a plastic abrasion resistant protective sleeve for covering a radiator hose. The sleeve of the invention has an annularly corrugated external surface comprising a plurality of projections and troughs formed in said sleeve. The projections are substantially evenly distributed and have a substantially uniform size. The sleeve has a slit along its longitudinal axis which provides for easy application to or removal from the hose, and is made of plastic that is substantially unaffected by high temperatures. A method of using said protective sleeve for protecting a radiator hose from abrasion also is provided.

Abstract: A method of making blow-molded perforated tubing and the tubing made by said method is provided. In the method of the invention, hollow-walled protuberances are blow molded into the side of the tubing as the tubing is formed and perforations are formed by cutting the hollow-walled protuberances.

Abstract: A convoluted hose construction comprised of an elongated helically wound elastomeric strip is provided and has first and second connecting means defining opposite side edge portions of the strip for holding the strip in its helically wound relation; and, the connecting means assures that the hose construction is held together in a high strength manner with maximum flexibility while using a minimum amount of material.
