polyol esters : DAMAN ORGANOMERS markets a complete line of neopolyol esters ranging from a viscosity (40 C) of 6 to 60 centistokes. These products are made by reacting short to long chain carboxylic acids with neopentyl polyols such as neopentyl glycol, trimethylopropane, and penta-erythritol. As a class, Polyol Esters are the best in terms of thermal stability being better than dibasic acid esters of the same viscosity. Although the DIOLUBE line comprises a rather large range of viscosities, if necessary, Daman Organomers can and will design molecules that meet your applications requirements.

 

APPLICATIONS

DIOLUBE POLYOL ESTERS find applications as base stocks in wide variety of industrial applications. Originally developed for the demanding requirements of jet engines, neopolyol esters have now found extensive applications in the formulation of automotive crankcase and transmission oils, compressor oils, refrigeration lubricants, hydraulic fluids, heat transfer fluids, dielectrics and textile lubricants, as well as many others.
