Product Application of 2,2-Dimethyl-1,3-propanediol CAS# 126-30-7
Neopentyl glycol is a versatile polyhydric alcohol raw material widely deployed across multiple downstream industries:
- Resin Production: Serves as core plasticizer feedstock for manufacturing unsaturated polyester resin, solvent-free alkyd resin, polyurethane foam and polyurethane elastomer.
- Fine Chemical & Lubricant Industry: Used as functional additive for premium lubricant goods and key intermediate for varied fine chemical synthesis.
- Petrochemical Separation: Works as high-performance selective solvent to separate aromatic hydrocarbons from cycloalkane components.
- Coating Manufacturing: Primary raw material for amino baking varnish; the finished coating maintains stable gloss and avoids yellowing thanks to the raw material’s superior anti-water, anti-chemical and weather-resistant traits.
- Agrochemical & Auxiliary Sector: Applied as synthetic starting material for corrosion inhibitors, chemical stabilizers and pesticide intermediates.
