Polyol Esters Additive

Polyol Esters:

  • Polyol esters are made from organic carboxylic acids and neo-polyols. Neo-polyols have a thermally and oxidative stable carbon center surrounded by two or more hydroxyl groups. The neo- polyol is reacted with natural or synthetic acids to make a polyol ester. The acid feed stocks determine characteristics such as polarity, lubricity, biodegradability and bio-based content. Many types of polyol esters are manufactured, and each is optimized for high or low temperature properties, viscosity, volatility, fire resistance, or even low cost. Polyol esters are well known for their outstanding high temperature performance.

Applications:

  • Polyol esters are the preferred base fluid for jet turbine lubricants, compressor oils, oven chain lubricants, fire resistant hydraulic fluids and high temperature greases. Some also remain liquid at extremely low temperatures and are used in refrigeration oils and arctic lubricants.
