  • Patent number: 6821632
    Abstract: In a composite of vulcanizable rubber or rubber-like composition with one or more metal reinforcement elements embedded therein, the metal reinforcement element is coated with a polymer or non-cured rubber composition compatible with and co-polymerizable, co-vulcanizable or crosslinkable with said vulcanizable ruber composition to be reinforced, and additionally bearing functional groups either covalently bonding to the metal surface of said reinforcement element or forming covalent bonds with the outward directed first functional groups of a mono- or multimolecular layer of a bifunctional adhesion promoter intercalated between said metal and said coating and bound to said metal by its second functional groups. A cured rubber or rubber-like product, for instance a pneumatic tire, is obtained by vulcanization of such a composite.

  • Patent number: 6818305
    Abstract: A molding method and a metal-covered plastic component such as partial or entire fascia, body side moldings, and the like, which have bright surface requirements and which includes a film sheet and a one-piece thermoplastic elastomeric structural carrier are provided. The film sheet includes a decorative layer of metal such as chrome. A plastic layer of the film sheet on which the layer of metal is formed is selected from a group consisting of polyester, polyurethane and polycarbonate. A bottom contact surface of the film sheet bonds with a front contact surface of the structural carrier by diffusion between the contact surfaces thereof within a mold cavity of an injection mold separate from the step of forming a preform which is securely positioned within the injection mold during injection molding to form the plastic part.

  • Patent number: 6776997
    Abstract: A combination of a low flexural modulus and low crystallinity polyolefin and a functionalized polyolefin were found to result in an olefin composition with excellent adhesion to metals and polar polymers (e.g. polyesters, polyamides, etc) especially fibers therefrom. When these two polyolefins were added to a thermoplastic vulcanizate (e.g. used to partially or fully replace the semicrystalline polyolefin of a thermoplastic vulcanizate), the thermoplastic vulcanizate was found to have the necessary adhesion to form fiber reinforced thermoplastic vulcanizate.
