Neopentyl Polyol Ester

Short Description:

Saturated Polyol ester — Neopentyl Polyol Ester, NPE
Type: RJ-1408, RJ-1409
Appearance: Colorless or yellowish transparent oily liquid
Chemical Properties: Neopentyl polyol esters have excellent high and low temperature properties, high flash point and low pour point. It can be used as type II aircraft engine oil, high temperature chain oil, synthetic air compressor oil and refrigerating machine oil base oil compatible with environmentally friendly refrigerants; it can also be formulated with polyα-olefin oil to improve the rubber It has the defects of shrinkage and poor compatibility with additives. It is used as a base oil for internal combustion engine oil, gear oil and other oils.
