ABSTRACT:
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.
