  • Adhesive coated slabs for sole manufacture in footwear assemblies
    Publication number: 20060057396
    Abstract: A slab material for the formation of soles for footwear assemblies which comprises an unmolded sole material having an upper surface, an inner ethylene copolymer based adhesive interfaced with the upper surface of the sole material and an outer thermoplastic polyurethane based adhesive interfaced with the inner adhesive. The outer adhesive is selected from the group consisting of thermoplastic polyurethanes, acrylic modified polyurethanes and acrylate modified polyurethanes.
    Type: Application

  • Composition of coextruded adhesive film to bond non-polar to polar surfaces
    Publication number: 20050069716
    Abstract: A two-layered adhesive film for bonding non-polar material such as Styrene-butadiene-rubber (SBR), natural rubber or ethylene copolymers to polar materials such as PVC, polyurethane, polyamide or polyester. The film comprises a thermoplastic polyurethane based adhesive layer adapted to bond to the polar material; and an ethylene copolymer based adhesive layer adapted to bond to the non-polar material. The two adhesive layers are interfacially bonded by coextrusion.
