Toxicological data
1. Irritation: Repeated application can cause extensive necrosis of animal skin. The liquid is significantly irritating to the eyes.
2.Materials and casting materials, etc. Chlorohydrin rubber produced with epichlorohydrin as raw material is a new type of rubber. It is not easy to expand in ordinary oils and ordinary solvents. It has greater flexibility at low temperatures without plasticizers and is superior to nitrile and chlorine. Some unique features of butyl and butyl rubber. In addition, 3-chloro-1,2-epoxypropane can also be used as a plasticizer, fiber treatment agent, stabilizer, insecticide and fungicide, pharmaceutical raw material, etc.
2. It is an important raw material and intermediate for organic synthesis. Used in the production of epoxy resin and as a diluent for epoxy resin. It is also used in the manufacture of glycerin, nitroglycerin explosives, fiberglass, glyceryl methacrylate, chlorohydrin rubber, glycidyl derivatives, surfactants, electrical insulation products, etc. It is also a common raw material for manufacturing a variety of adhesives, medicines, pesticides, plasticizers, ion exchange resins and other products. It is also used as a solvent for adhesives, coatings, paints, rubber, resins, cellulose esters and cellulose ethers.
