Use to
It is mainly used as plasticizer for the production of unsaturated polyester resin, oil-free alkyd resin, polyurethane foam plastic and elastomer, additive for advanced lubricating oil and other fine chemicals. Neopentyl glycol can be used for selective separation of aromatic hydrocarbons and cycloalkyl hydrocarbons. Neopentyl glycol has chemical resistance and weather resistance. Its amino baking paint has good gloss retention and does not turn yellow. It can also be used as a raw material for the production of polymerization inhibitors, stabilizers and insecticides.
