Vinyl acetate copolymers; in aqueous dispersion, in primary forms

HS v2022 Code: 390521

About vinyl acetate copolymers; in aqueous dispersion, in primary forms

HS code 390521 covers vinyl acetate copolymers in aqueous dispersion, which are a type of synthetic polymer with a wide range of industrial and commercial applications. These versatile materials play a crucial role in the production of adhesives, paints, coatings, and various other products that are essential for numerous industries, contributing significantly to the global economy.

Production process

Vinyl acetate copolymers are typically produced through a polymerization process, where vinyl acetate monomers are combined with other monomers, such as ethylene or acrylic acid, to create the desired copolymer. The polymerization reaction is often carried out in an aqueous medium, resulting in a stable dispersion of the copolymer particles. This production method allows for the creation of a wide range of vinyl acetate copolymer formulations with tailored properties to meet the specific needs of various applications.

Production inputs

The main inputs required for the production of vinyl acetate copolymers in aqueous dispersion include vinyl acetate monomer, other co-monomers (e.g., ethylene, acrylic acid), initiators, surfactants, and water. Additionally, specialized production equipment, such as reactors, mixing tanks, and drying systems, are necessary to facilitate the polymerization process and ensure the desired product characteristics.

Production outputs

Vinyl acetate copolymers in aqueous dispersion (HS code 390521 Vinyl acetate copolymers; in aqueous dispersion, in primary forms) are widely used as raw materials in the manufacture of a variety of products, including adhesives, paints, coatings, sealants, and textiles. These copolymers are often consumed by industries classified under other HS codes, such as 3506 Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale, not exceeding a net weight of 1 kg, 3208 (Paints and varnishes (including enamels and lacquers) based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in a non-aqueous medium; solutions as defined in note 4 to this chapter), and 5903 Textile fabrics impregnated, coated, covered or laminated with plastics, other than those of heading 5902, among others.
