Roll of Base Oil in Lubricants and Trends of High Flash Point Type Lubricants

Abstract

Lubricant is a very important component of machine which contributes to their stable operations. Its basic performance mostly depends on the base oil that composes 80 to 90% of the Lubricant itself. In addition to above mentioned, there are many kinds of base oil and we have to choose the most appropriate one for operating environment of Lubricant. On the other hand, there is a growing need for high-performance Lubricant corresponding to the enhancement of laws and regulations all over the world. In this review, we summarize the property and application of base oil, in particular, the mineral, synthetic and vegetable types. Furthermore, we introduce an example of the countermeasures and its results for the Fire Defense Law compliance, in consideration of the change of the Lubricant to high flash point type.
