Vinyl acetate copolymers; in aqueous dispersion, in primary forms

HS v2017 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 materials are essential components in the production of paints, adhesives, textiles, and various other products, making them a crucial part of the global manufacturing and construction industries.

Production process

Vinyl acetate copolymers are typically produced through a process of emulsion polymerization. This involves the copolymerization of vinyl acetate with other monomers, such as ethylene or acrylic esters, in an aqueous medium. The resulting polymer dispersion is then stabilized and formulated for specific end-use applications.

Production inputs

The main inputs required for the production of vinyl acetate copolymers include vinyl acetate monomer, co-monomers (e.g., ethylene, acrylic esters), initiators, emulsifiers, and other additives. Additionally, the production process requires specialized equipment, such as reactors, mixing tanks, and drying facilities.

Production outputs

Vinyl acetate copolymers produced under HS code 390521 are used in a wide range of applications, including 320910 Paints and varnishes, 350610 Prepared glues and other prepared adhesives, 590310 Textile fabrics impregnated, coated, covered or laminated with plastics, and 391810 Floor coverings of plastics. These materials are often further processed and incorporated into various consumer and industrial products.
