<p><P>PROBLEM TO BE SOLVED: To surely adhere and bond a non-polar surface such as styrene-butadiene rubber (SBR) or ethylene-vinyl acetate copolymer (EVA) to a polar surface of PVC, polyurethane, polyamide, polyester, or the like. <P>SOLUTION: The invention relates to 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, polyester or the like. 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. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
