Vinyl Acetate Monomer (VAM)

Vinyl Acetate Monomer (VAM) is a colorless flammable liquid with sweet ether flavor. There are several different raw materials such as acetylene method, ethylene method, acetaldehyde acetic anhydride and so on. The route of ethylene raw materials is different according to the process, and there are different methods such as ethylene gas phase method and ethylene liquid phase method.

General properties

Vinyl Acetate Monomer (VAM) is miscible with ethanol, soluble in ether, acetone, chloroform, carbon tetrachloride and other organic solvents, insoluble in water. It is easily polymerized into a transparent solid by the action of heat, light or trace amounts of peroxide. Usually hydroquinone or diphenylamine is added as a stabilizer, and the storage time of pure products without stabilizers should not exceed 24h.iscible with ethanol, soluble in ether, acetone, chloroform, carbon tetrachloride and other organic solvents, insoluble in water.

Applications

Vinyl Acetate Monomer (VAM) is the main raw material for the manufacture of synthetic fiber vinylon. Vinyl Acetate Monomer (VAM) is polymerized by itself or copolymerized with fractionated monomers to obtain polyvinyl alcohol, vinyl acetate-ethylene copolymer (EVA), vinyl acetate-vinyl chloride copolymer (EVC), vinyl acetate-acrylonitrile fiber, vinyl acetate-acrylate copolymer. They all have important industrial uses, widely used as binders, architectural coatings, textile sizing and finishing agents, paper reinforcements, and for the manufacture of safety glass.

Vinyl acetate reacts with ethanol and bromine to prepare bromoacetaldehyde diethanol. This is an intermediate of the drug methiimidazole.

Packages

Package: In 190KG drum or 22MT ISO Tank.

Storage

Usually hydroquinone or diphenylamine is added as a stabilizer, and the storage time of pure products without stabilizers should not exceed 24h.
