Poly(vinyl alcohol); whether or not containing unhydrolysed acetate groups

HS v2017 Code: 390530

About poly(vinyl alcohol); whether or not containing unhydrolysed acetate groups

HS code 390530 covers poly(vinyl alcohol), a versatile synthetic polymer with a wide range of industrial and commercial applications. This material is known for its excellent film-forming, emulsifying, and adhesive properties, making it a crucial component in various manufacturing processes. The global poly(vinyl alcohol) market has experienced steady growth in recent years, driven by increasing demand from industries such as packaging, textiles, and construction.

Production process

Poly(vinyl alcohol) is primarily produced through the hydrolysis of poly(vinyl acetate). This process involves the conversion of the acetate groups in the polymer chain to hydroxyl groups, resulting in the formation of the final poly(vinyl alcohol) product. The degree of hydrolysis can be controlled to produce different grades of the material, each with unique properties and applications.

Production inputs

The main raw material required for the production of poly(vinyl alcohol) is poly(vinyl acetate), which is typically derived from the polymerization of vinyl acetate. Additionally, the manufacturing process may involve the use of various solvents, catalysts, and other additives to control the properties of the final product. Specialized production equipment, such as reactors, distillation columns, and drying systems, are also essential for the efficient and consistent production of poly(vinyl alcohol).

Production outputs

Poly(vinyl alcohol) produced under HS code 390530 has a wide range of applications, including the manufacture of 392010 (Poly(vinyl alcohol) film), 391690 (Poly(vinyl alcohol) tubes, pipes, and hoses), and 391810 (Poly(vinyl alcohol) floor coverings). The material is also used in the production of adhesives, emulsifiers, and textile sizing agents, as well as in the paper, cosmetics, and pharmaceutical industries. The output of this industry is often consumed by manufacturers operating under various other HS codes, depending on the specific application.
