Abstract
Fluoroelastomers are well known for their resistance to heat and fluids, and have become major material for crankcase oil sealers. On the other hand, new additive formulations are developed for engine lubricants used for fuel economic gasoline engines. In this paper, the effects of those additives on properties of fluoroelastomers are investigated. The results of the immersion tests of both test plaques and oil sealer products indicates that dithiocarbamates, friction modifier, have hardening effects on fluoroelastomers. The fluoroelastomer deterioration mechanism is presumed by analysis of elastomer samples after immersion in oil.
