- Product Highlights
Diesters are low to medium viscosity synthetic base stocks that have two ester groups. Most diesters are made from a dibasic acid combined with monofunctional alcohols, while a polyol diester is made from a synthetic glycol and monofunctional acids.
Diesters are known for outstanding low temperature properties, lubricity and solvency. The polar ester groups provide excellent high temperature stability and low temperature fluidity. When comparing diesters to hydrocarbon oils and other synthetics with the same viscosity, a diester fluid will have a higher flash point, lower volatility and better thermal stability. Diesters improve additive solubility and seal conditioning, while offering natural high viscosity index thats boosts lubrication efficiency. Synthetic esters are high performance base stock components used in the formulation of synthetic engine, transmission and racing oils due to their low NOACK volatility, thermal stability and compatibility with mineral oil and PAO base oils. Their polar nature conditions seals, improves additive solubility and reduces deposit formation solubilizing sludge, soot and other oxidation byproducts. Synthetic esters provide shear stable high viscosity index which enhances operating efficiency and fuel economy.
The global automotive industry continues to demand lower viscosity motor oils that provide better fuel efficiency under more severe conditions, while maintaining wear protection and long drain intervals. Engine and transmission oils must flow under cold weather conditions to lubricate on startup and also provide lubricating film strength under high temperature/high shear conditions. High quality synthetic esters combined with PAO and Group III mineral oils deliver advanced performance for the next generation of synthetic engine oils.
Diesters and polyol esters are particularly favored for two stroke engines oils that require an environmentally friendly, clean burning fuel component that provides excellent lubricity and inhibits deposit formation.
