Silicone rubber-ethylene vinyl acetate adhesive laminates and preparation thereof

A laminate comprising a crosslinked ethylene-vinyl acetate copolymer ply adhered to a ply of crosslinked silicone rubber, the interfacial surfaces of said plies being in contact with a powder bonding agent in an amount of 0.00001-0.001 gram per square inch of planar surface, said bonding agent being silica or an admixture of silica with a material selected from the group consisting of silane and polyfunctional monomer.

An insulated ignition wire comprising a central conductor, a first insulating material surrounding the central conductor and a second insulating material surrounding the first insulating material and bonded thereto, wherein said first insulating material is crosslinked ethylene-vinyl acetate and said second insulating material is crosslinked silicone rubber and wherein the interfacial surfaces of said first and second insulating material are bonded by a powder bonding agent in an amount of 0.00001-0.001 gram per square inch of surface, said bonding agent being silica or a mixture of silica and a member of the group consisting of a silane and polyfunctional monomer.
