Product Introduction
 

VAM

Vinyl Acete

FEATURES
 

Vinyl Acetate Monomer ( VAM ) is an active, colorless, and liquid phase chemical, produced by the vapor phase reaction of Ethylene, Acetic Acid and Oxygen over a catalyst. Stabilized with hydroquinone inhibitor for storage.



APPLICATION

Polyvinyl Acetate

The emulsion polymer is used as adhesive for paper, wood, non-woven fabrics, rug backing or used as material of paint. The polymer prepared by solution polymerization is used as a base material of chewing gum.

Polyvinyl Alcohol

Used as textile warp and yarn size, laminating adhesive, emulsifying agent and films.

Vinyl Acetate-Ethylene Copolymer

High ethylene content copolymer EVA resin is used as packaging film, blow-molded and hot melt products. Low ethylene content copolymer EVA emulsion is used as adhesive, paint and paper coating.

Vinyl Acetate-Vinyl Chloride Copolymer

  • Used as LP records and plastic floor tile.
  • Ethylene-Vinyl Acetate- Vinyl Chloride Terpolymer
  • Used as adhensive with its excellent water resistance and fire retardant characteristics.
  • Polyvinyl Butyral
  • Used as interlayer of safety glass.

VAEP

Vinyl Acetate-Ethylene Redispersible Power

 

FEATURES 

VAE Redispersible Powder is a white free-flowing Vinyl Acetate-Ethylene copolymer base powder, readily redispersible in water to form stable emulsion. It combines the original characteristics of EVA emulsion with the special property of free flowing powder, and it is easy and convenient to handle and storage. Dry mixing with other powder materials such as cement, sand and aggregate at the factory can ensure consistent and reliable performance at the work site.

 
APPLICATION

VAEP
is used in combination of cement and plaster, or as a sole binder in other dry-mix formulation. VAE improves adhesion, flexural strength, abrasion resistance and workability in a variety of product sold in dry powder form, including thin-set mortars, tile adhesives, grout, finishing plasters and troweling compounds.
VAEP
is a general purpose copolymer powder that can be used in the building materials and adhesives field as a binder component. In the general formulation the amount of VAE is about 5 to 20% based on the weight of cement.
