Neopentyl Glycol

Neopentylglycol (NPG) is a unique polyalcohol offering superior performance advantages in many end-use applications due to its high chemical and thermal stability.
Neopentylglycol (2, 2-dimethyl-1, 3-propanediol) is a unique diol offering superior performance advantages in many end-use applications. These advantages are derived from its chemical structure. The location of the hydroxyl groups on primary carbon atoms allows rapid esterification. Additionally, the two methyl groups, instead of the usual two hydrogen atoms, on the alpha carbon atom are responsible for the high chemical and thermal stability of Neopentylglycol and it derivatives.
Application
Neopentylglycol (NPG), or 2, 2-dimethyl-1, 3-propanediol,is mainly used as a building block in polyester resins for coatings, unsaturated polyesters, lubricants and plasticizers.
