Both layers having a perfluoro rubber layer and other rubber layers include a laminate in the form of an O-ring, an angle ring, a rubber roll, a diaphragm, a rubber hose, a rubber tube, or a chemical stopper, which is vulcanized by inserting an adhesive layer containing a polyfunctional compound. For example, a polyfunctional compound is applied to at least one side of the perfluoro rubber layer and the other rubber layer, and the two layers are overlapped so that the coated surface faces the other layer, followed by vulcanization and adhesion of both layers. This improves the interlayer adhesion of the laminate containing the perfluoro rubber layer and other rubber layers. |
