UCON™ TPEG 990

ISO 100/150 polyalkylene glycol base stock with high temperature stability.
Product Overview
UCON™ TPEG 990 is a polymer of ethylene oxide and used in industrial applications as a lubricant base, as a chemical intermediate, and as an additive for the properties they impart. It has a viscosity of 123 cSt @ 40 °C. UCON™ TPEG 990 is engineered to remain a liquid at temperatures that other polyethylene oxides become a solid wax.
