EpichlorohydrinCAS#106-89-8
1. Versatile Applications: Essential in producing epoxy resins, nitroglycerin, fiberglass, and a wide range of industrial chemicals.
2. Superior Epoxy Resins: Provides epoxy resins with excellent adhesive properties, chemical corrosion resistance, and minimal shrinkage for protective coatings and bonding agents.
3. Advanced Rubber Properties: Produces chlorohydrin rubber with superior flexibility at low temperatures and excellent resistance to oils and solvents.
4. Key Raw Material: Acts as a critical intermediate in glycerol synthesis and as a solvent for cellulose derivatives, making it indispensable in various industries.
Epichlorohydrin serves as a key intermediate in glycerol synthesis and functions as the primary raw material for manufacturing epoxy resins, nitroglycerin explosives, fiberglass, and electrical insulation products. Additionally, it acts as a solvent for mixtures containing cellulose esters, resins, and cellulose ethers. This versatile compound also serves as a fundamental material in producing surfactants, pharmaceuticals, agricultural chemicals, coatings, adhesives, ion exchange resins, plasticizers, glycerol derivatives, glycidyl derivatives, and chlorohydrin rubber.
Epoxy resins manufactured using epichlorohydrin and bisphenol A as principal components exhibit exceptional adhesive properties, minimal shrinkage, resistance to chemical corrosion, and excellent stability. These characteristics make them valuable for diverse applications including protective coatings, bonding agents, reinforcement materials, and casting compounds.
The chlorohydrin rubber derived from epichlorohydrin represents an advanced elastomer with distinctive properties. It demonstrates remarkable resistance to swelling in conventional oils and common solvents, maintains superior flexibility at low temperatures without requiring plasticizers, and possesses unique performance characteristics that surpass those of nitrile, chloroprene, and butyl rubbers in specific applications.
