Propylene oxide (also known as propylene oxide, methyloxirane, 1,2-epoxypropane) is a colorless, transparent, low-boiling, volatile and flammable liquid with an ether-like odor.The industrial product is a racemic mixture of two optical isomers.The molecule contains a highly reactive three-membered epoxy ring, making it chemically active and an important intermediate in organic synthesis.

1. Core Raw Materials：Production of polyether polyols (key raw materials for polyurethane foams, thermal insulation materials, elastomers, adhesives and coatings) and propylene glycol.
2. Fine Chemicals：Manufacture of nonionic surfactants, emulsifiers, wetting agents, detergents, fungicides, fumigants, plasticizers, synthetic resins, unsaturated polyesters, etc.
3. Other Fields：Intermediates for pharmaceuticals and pesticides, fumigants in the food industry, and raw materials for organic synthesis reactions.
