TRIEST PEO-0611 is a hydrolytically and thermally stable polyol ester synthesized from the reaction of pentaerythritol with oleic acid to form pentaerythritol oleate. It has low volatility and a high viscosity index of 170, making it resistant to high-temperature conditions commonly found in machining operations. It is recommended for the formulation of industrial fluids, such as metalworking fluids, greases, hydraulic fluids, and steel rolling oils, providing high lubrication and optimal performance.
