<p>A method of bonding a layer of a fluoroelastomer compound to a layer of a butadiene-acrylonitrile polymer compound comprises incorporating a polysulphidic silane compound into either or both compounds, prior to bonding the layers together, and vulcanising the layers in contact with each other, in which the amount of polysulphidic silane compound is from about 1 to about 5 parts by weight per 100 parts by weight of fluoroelastomer and or butadiene-acrylonitrile polymer in the compounds. The resultant laminate may be used as a hose, the fluoroelastomer being the inner layer.</p> |
