A rubber laminate of a fluororubber layer and an NBR layer firmly bonded through vulcanization is provided. The fluororubber layer is made of a fluororubber compound containing a peroxide vulcanizing agent, polyol vulcanizing agent, or polyamine vulcanizing agent. In the case where the fluororubber compound contains a peroxide vulcanizing agent, it further contains a metal oxide. The NBR layer is made of a functional NBR having a specific functional group which is determined according to the vulcanizing agent contained in the fluororubber compound. In the case where the fluororubber compound contains a peroxide vulcanizing agent or polyol vulcanizing agent, the NBR compound further contains a metal oxide. The two layers are firmly bonded through vulcanization. This rubber laminate is used for automotive fuel hoses and fuel pump diaphragms.
An automotive fuel hose or fuel pump diaphragm made of a rubber laminate which comprises a fluororubber layer and a butadiene-acrylonitrile rubber (NBR) layer bonded together through vulcanization,
An automotive fuel hose or fuel pump diaphragm made of a rubber laminate which comprises a flurorubber layer and an NBR layer binded together through vulcanization,
An automotive fuel hose or fuel pump diaphragm made of a rubber laminate which comprises a fluororubber layer and an NBR layer bonded together through vulcanization,
