Abstract
Fluoro rubber (FKM) is commonly applied to oil seals which are used in areas such as gasoline engines or associated components that require high heat resistance. Based on this, the recent high temperature performance engines and engine oil improvements are remarkable and present a real challenge for elastomeric materials.
FKM can be expensive and can sometimes exceeds the requirements depending on the engine heat condition.
This report will show the development and evaluation of heat resistant acrylic rubber designed for oil seal applications of today's high temperature engines with FKM type performance and acrylic rubber type value.
Rubber hardness was mainly used as an evaluation index to measure heat resistance and durability in the material development process to verify the effect.
Oil seals with this improved material has 3 times the durable life to the current acrylic rubber material when compared in the oil seal bench test.
This improved ACM material life, as an oil seal, was confirmed in actual engine testing and was adopted in current vehicle applications.
