In order to reduce rubber cost of high-speed oil seals for automobiles, performance requirements for rubber materials used in high-speed oil seals are determined according to the application locations and operation conditions. The acrylic rubber formula is analyzed and designed from the aspects of raw rubber selection, reinforcement system, vulcanization system, aging system, wear resistance system, and processing system. Finally, the acrylic rubber formula for high-speed oil seals in automobiles is developed. The test shows that the developed acrylic rubber fully meets the performance requirements of rubber materials for high-speed oil seals, and can replace the expensive fluororubber material for large-scale application in automotive high-speed oil seals.
