Chemical products  Neopentyl Glycol usage

Mainly used in the manufacture of resins, plasticizers and surfactants; neopentyl glycol has a wide range of uses, mainly as a plasticizer for the production of unsaturated polyester resins, oil-free alkyd resins, polyurethane foams and elastomers. Lubricating oil additives and other fine chemicals. Neopentyl glycol is an excellent solvent for the selective separation of aromatic hydrocarbons and cycloalkyl hydrocarbons. Neopentyl glycol has water resistance, chemical resistance, and weather resistance. The amino baking varnish 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 pesticides. Plasticizer. Organic Synthesis. Polyester synthetic raw material.
