Epichlorohydrin serves as a key intermediate for glycerol synthesis and a primary raw material for epoxy resins, nitroglycerin explosives, fiberglass, and electrical insulation products. It is also employed as a component in blends of cellulose esters, resins, and cellulose ethers. In addition, it is used to manufacture surfactants, pharmaceuticals, pesticides, coatings, adhesives, ion exchange resins, plasticizers, glycerol derivatives, glycidyl derivatives, and chlorohydrin rubbers. Epoxy resins produced from epichlorohydrin and bisphenol A feature strong adhesion, low shrinkage, chemical resistance, and high stability, making them widely used in coatings, adhesives, reinforcing materials, and casting materials. Chlorohydrin rubber derived from epichlorohydrin is a high-performance elastomer that resists swelling in common oils and solvents, remains flexible at low temperatures without plasticizers, and offers unique advantages over nitrile, neoprene, and butyl rubbers.
