Vinyl Acetate Monomer (VAM)
[Raw Material] - Acetic acid, Ethylene
[Finished products] - Food additives (Coagulant, Brine), Chewing gum, Wood glue
Vinyl acetate monomer (VAM) is a compound made from acetic acid and ethylene and vinyl acetate resin is made by connecting many varieties of acetic acids.
This vinyl acetate monomer resin has a role in food additives and it is included in many of the foods we eat in our everyday life.
Vinyl acetate monomer is mainly used in Chinese noodles, tofu and chewing gum.
For Chinese noodles it is used to give the noodles texture and flavor. For tofu it is used has a coagulant to help give it shape.
For chewing gum, it used to create the gum base which is mixed with spicy and sweet flavors in making gum. Vinyl acetate monomer resin is a key ingredient of this gum base.
Vinyl acetate monomer is also used in non-food-products. A primary purpose is in the production of wood glue.
Wood glue is made by mixing water and vinyl acetate monomer resin. At first the wood glue is soft since the vinyl acetate monomer resin does not melt in water but once it is bonded with objects the moisture will evaporate and become hard.
Wood glue therefore effectively uses this characteristic of vinyl acetate monomer.
