Acrylic polymers; (other than polymethyl methacrylate), in primary forms

HS code 390690 covers a diverse range of acrylic polymers, excluding polymethyl methacrylate, in their primary forms. These materials are widely used across various industries, from construction and automotive to consumer goods and medical applications. Acrylic polymers offer a unique combination of properties, including transparency, durability, and versatility, making them an essential component in the global manufacturing landscape.

The production of acrylic polymers under HS code 390690 typically involves polymerization processes, where monomers such as acrylates or methacrylates are combined to form long-chain polymer molecules. This can be achieved through techniques like bulk polymerization, solution polymerization, or emulsion polymerization, depending on the specific requirements of the final product. The resulting polymer is then processed into various primary forms, such as pellets, granules, or powders, ready for further downstream applications.

The main inputs required for the production of acrylic polymers under HS code 390690 include petrochemical-based monomers, such as 290620 acrylic acid or 290916 methyl methacrylate, as well as various catalysts, initiators, and other additives that facilitate the polymerization process. Additionally, specialized production equipment, such as reactors, extruders, and drying systems, are essential for the efficient and consistent manufacturing of these materials.

The primary outputs of the industry covered by HS code 390690 are diverse acrylic polymer products in their primary forms, which can be further processed and transformed into a wide range of end-use applications. These acrylic polymers may be consumed by industries such as 392010 Plates, sheets, film, foil and strip, of polymers of vinyl chloride, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392030 Plates, sheets, film, foil and strip, of polymers of styrene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, and 392091 Plates, sheets, film, foil and strip, of polymers of vinyl chloride or of other halogenated olefins, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
