Details

PRODUCT INTRODUCTION

Neopentyl glycol is an organic chemical compound. It is used in the synthesis of polyesters, paints, lubricants, and plasticizers. When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water. By esterification reaction with fatty or carboxylic acids, synthetic lubricating esters with reduced potential for oxidation or hydrolysis, compared to natural esters, can be produced.

PHYSICAL AND CHEMICAL PROPERTIES

Appearance: crystalline solid
Structure:
NPG Purity,% ≥ 99.0
Moisture ,w/% ≤0.3
Chroma (50% aqueous solution)(Pt-Co) ≤ 15
Acid value (mg KOH/g) ≤0.1

APPLICATIONS

NPG is used as a building block for the production of polyurethane adhesive resins (polyester polyol and polycarbonate diol) providing flexibility and adhesion.

Coatings

NPG is mainly used as a building block for coating resins such as saturated polyesters (major application in powder coatings), alkyds (e.g. Coating metal furniture and fixtures), unsaturated polyesters (e.g. artificial marble and gelcoat for boats), and finally for the production of polyurethane resins (polyester polyol and polycarbonate diol).

NPG provides high hydrolytic stability, high UV stability (UVA/UVB), weatherability, adhesion and a good balance between hardness and flexibility.

Others

NPG is utilized in the production of polyester lubricants and plasticizers.
