For application at high temperature in non-aqueous lubricants, ESTILUBE products with a low iodine value are recommended. They have the best oxidation stability, and the saturated structure of the molecules reduces the risk for formation of carbon residues. For aqueous products, where the lubricant normally is exposed for less thermal stress, the ESTILUBE esters with a higher iodine value may be applied. ESTILUBE esters with a low viscosity and a low iodine value are applied as lubricant additives in stamping fluids based on low-viscosity hydrocarbons.
