Neopentyl glycol is mainly used in the production of saturated / unsaturated polyester resins, oil-free alkyd resins. polyester polyols, esters for synthetic lubricants, polyurethane foam and elastomer plasticizers, additives for advanced lubricants and other fine chemicals. NPG is combined into the molecular chain of polyester resin, which makes the resin with excellent chemical stability, hydrolysis resistance, weather resistance, corrosion resistance, aging resistance and thermal stability. These properties are
