Neopentyl Polyol Ester NPE
Premium synthetic ester base oil with superior high- and low-temperature performance and oxidation stability
Product Overview
ARNOCO Neopentyl Polyol Esters (NPE) are high-performance synthetic ester base oils produced by esterifying neopentyl glycol with various fatty acids. Featuring exceptional low- and high-temperature performance, superior oxidation stability, and low volatility, they are ideal base oils for premium lubricants such as aviation oils, compressor oils, and high-temperature chain oils.
Widely used in aircraft engine oils, gas turbine oils, screw compressor oils, and high-temperature heat transfer fluids. Ideally suited for demanding applications requiring extreme temperature resistance and extended service life.
Core Advantages
Excellent high and low temperature performance
Wide temperature range: resists decomposition at high temperatures and prevents freezing at low temperatures, ensuring consistent lubrication performance.
Superior Antioxidant
Stable molecular structure, strong antioxidant performance, long service life, and extended oil change intervals.
Low volatility
Low evaporation loss at high temperatures, low fuel consumption, and reduced refueling frequency
