    Neopentyl Polyol Ester(POE series,dividing into NPE series and DIPE series)

    Neopentyl polyol esters(synthetic saturated esters) have not beta hydrogens in the formula, which are more hydrolytically and thermally stable than diesters. The main types include neopentyl glycol ester, trimethylolpropane ester and pentaerythritol ester,dipentaerythritol ester,etc.

    Applications:

    With excellent high/low temperature property, high flash point and low pour point, the saturated polyol esters are suitable basefluid for high temperature chain oil, basefluid for synthetic polyol ester -high miscibility refrigeration lubricant which is compatible with the new alternative refrigerants satisfied with environmental protection requirement(e.g. HFC's Refrigerants such as R-134a,R-404a,R-407a,R-410a,R-507c)  , or important component for fully synthetic automobile engine oil 。

    1.NPE-2 (trimethylolpropane C6/C10 acids or trimethylolpropane C8/C10 acids )  is specially recommended   as the basefluid component for fully synthetic engine oil and gear oil, usually 

    2.NPE-3 is specially  recommended as basefluid for synthetic ester high temperature chain oil ,

    3.NPE-4,NPE-6,DIPE-68,DIPE-100 is special recommended as basefluid for #32, #68 ,#100 type synthetic polyol ester -high miscibility refrigeration lubricant.

    4.DIPE-220,DIPE-300 is mainly applied as basefluid with characteristics of high flash point,high viscosity, oxidatively stable, low deposit forming which suitable for formulating high temperature chain oil or greases ,for the reason of providing good detergency and oxidative stability to help keeping chains clear in the most demanding applications.

    Note: This series has been under exporting to Egypt,Chile, Venezuela , Turkey, Russia markets.

    Note: some physical and chemical properties can be adjusted to client  request accordingly.

    Packaging: 180KG/ galvanized iron drum or IBC tank of 900KG.

    Storage: Stored in dry and cool places.
