Bio-based Hydraulic Fluids

Abstract

Bio-based Hydraulic Fluids (BHFs) are currently formulated with vegetable oils (i.e. rapeseed, sun flower, corn, soybean, canola, coconut, etc.) and synthetic ester, such as polyol ester, and additive packages. Their lubrication properties are very similar to mineral oils and readily biodegradable and low toxic fluids. Some of the fluids have a limited operational capability such as a poor low temperature characteristics and oxidation stability. Many oil companies have developed bio-based fluids to eliminate the hazardous pollution caused by accidental oil spillage, which is especially important in environmentally sensitive applications such as construction. Another good reason to use bio-based hydraulic fluids is to develop a market for US grown agricultural feedstock and to reduce reliance on overseas petroleum crude oil.
