Neopentyl Glycol(NPG) CAS 126-30-7
Sinochem is a major Neopentyl Glycol & NPG supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Neopentyl Glycol & NPG.
NPG is a unique diol providing superior hydrolytic and UV stability to polymers. It’s key for high-performance polyester resins in coatings, offering excellent hardness and weather resistance. NPG also enhances synthetic lubricants and polyurethanes.
- Steric Hindrance: Its neopentyl structure provides excellent hydrolytic stability and resistance to degradation from heat and UV radiation in derived polymers.
- Enhanced Polyester Properties: NPG-based polyesters exhibit improved gloss retention, non-yellowing characteristics
- Alkyd Resins & Polyurethanes: Contributes to enhanced durability and performance in alkyd resins and various polyurethane applications.

Neopentyl Glycol Applications
1. NPG has a wide range of uses, mainly as a plasticizer for unsaturated polyester resins, oil-free alkyd resins, polyurethane foams and elastomers, as well as an additive for advanced lubricants and other fine chemicals.
2. NPG is an excellent solvent that can be used for the selective separation of aromatic hydrocarbons and cycloalkyl hydrocarbons.
3. NPG is resistant to water, chemicals and weathering. Amino baking varnish has good gloss retention and does not yellow.
4. It can also be used as a raw material for the production of inhibitors, stabilizers and pesticides.
