Fatty esters meet the most stringent requirements of the lubricants industry. They are used as lubricity improvers in applications like steel, copper and aluminum rolling. Furthermore they are used in neat oils and emulsions for cutting, grinding and drilling operations. Ester base stocks for industrial gear oils, meeting technical requirements of many standards and specifications. For greases Ester base stocks contribute to improved cold flow properties, lower volatility, good thermal stability, low noise level, good air realease and water separation. Esters are used in a wide range of environmental Lubricants. Taking the chemistry of esters into account and as well as the raw materials used, many Esters are eligible for Ecolabel registration.
