Acrylic rubber composition and process for its production |
摘要 |
<p>An acrylic rubber composition which forms a phosphorous inert coating on the surface of a metal member when in contact with the metal member under high temperature contains the acrylic rubber, a phosphite-based material and an acid acceptor which reacts with an acid substance in the composition. The acrylic rubber composition particularly exhibits its effect when used as a sealing member 10 for an oil filter 1 which filters engine oil. In such cases, the content of the phosphite-based material is preferably 8-20 parts by weight and that of the acid acceptor is preferably 1-10 parts by weight to 100 parts by weight of the acrylic rubber. <IMAGE></p> |
