Acetic Acid

It is one of the world’s most important chemicals and is a key raw material for the production of vinyl acetate monomer, acetic anhydride and the acetate esters.

Acetic acid is also used in the production of purified teraphthalic acid (PTA), which in turn is used to manufacture polyethylene terephthalate (PET). PET finds applications in the packaging, photographic film and magnetic tape sectors, polyester fibers (for polyester/cotton clothing blends) and bottles forwater and soft drinks, spirits, salad dressing as well as food trays and cups.


Caustic Soda

It is used in a wide range of applications part of our daily lives. Produced by the electrolysis of salt brine, Vinythai’s Caustic soda, or sodium hydroxide, is a strong base soluble in water. Vinythai produces and supplies caustic soda in liquid form (aqueous solution) available on a wide industrial scale and commercially available as 32% and 50% concentration under the main quality international standard.



It also called 2-aminoethanol or monoethanolamine (often abbreviated as ETA or MEA), is an organic chemical compound that is both a primary amine and a primary alcohol.

MEA is used in aqueous solutions for scrubbing certain acidic gases. It is used as feedstock in the production of detergents, emulsifiers, polishes, pharmaceuticals, corrosion inhibitors, chemical intermediates.


Styrene Monomer ( SM )

Styrene (vinyl benzene, styrene monomer SM) is a colorless to yellowish oily liquid with a distinctive aromatic odor. It is sparingly soluble in water but soluble in alcohols, ethers and carbon disulfide. This valuable monomer is flammable, reactive and toxic. Styrene Monomer is a light liquid. It has a low vapor pressure and high refractive index. It is chemically reactive and undergoes polymerization readily (by heat, light or peroxide catalysts). Polymerization results in volumetric shrinkage (17%) and exothermic heat (17.8 Kcal/mole).

Styrene Monomer is most commonly used in the production of valuable styrene homopolymers and copolymers, which are either solid (SPS) or expandable (EPS). Some SPS grades are used for the production of disposable transparent containers and EPS grades are useful in the fabrication of blocks for thermal insulation and boxes for vegetables and fruits. High Impact Polystyrene (HIPS) is polystyrene blended with rubber for better mechanical properties useful in the production of dairy products, packaging materials and sheets. The copolymers of SM with butadiene and/or acrylonitrile create valuable products combining characteristics of synthetic rubbers and strong plastics.
