3 Claims

1. A laminate, comprising an acrylonitrile-butadiene rubber layer comprising a composition and a saponified ethylene-vinyl acetate copolymer layer through an ethylene-vinyl acetate copolymer layer,

wherein the composition comprises an acrylonitrile-butadiene rubber; a silane-modified ethylene-vinyl acetate copolymer of 0 to 50 parts by mass with respect to 100 parts by mass of the acrylonitrile-butadiene rubber; and a filler of 100 to 300 parts by mass with respect to 100 parts by mass of the above acrylonitrile-butadiene rubber,

wherein the thickness of the layer of the saponified ethylene-vinyl acetate copolymer layer is 0.1 to 30 mm, and

wherein the acrylonitrile-butadiene rubber layer is crosslinked.
