<p>A laminate, which is in the form of an O-ring, a square ring, a rubber roll, a diaphragm, a rubber hose, a rubber tube or a vial stopper, comprising a layer of a perfluororubber, a layer of other rubber and an adhesive layer containing a polyfunctional compound which adheres the both rubber layers by vulcanization us produced by coating a polyfunctional compound on a surface of at least one of the layer of perfluororubber and the layer of the other rubber, laminating the layers with the coated surface facing the other layer, and vulcanizing the layers to adhere them. Thereby, the adhesion strength between the layer of perfluororubber and the layer of the other rubber is improved. <IMAGE></p> |
