Vinyl chloride polymers; waste, parings and scrap

HS code 391530 covers vinyl chloride polymers, which are a type of thermoplastic resin derived from the polymerization of vinyl chloride. These polymers are widely used in a variety of industries due to their durability, chemical resistance, and versatility. The global vinyl chloride polymer market is a significant component of the broader plastics and chemicals industry, playing a crucial role in the manufacturing of a wide range of products, from construction materials to consumer goods.

The production of vinyl chloride polymers typically involves several key steps. First, vinyl chloride monomers are produced through the reaction of ethylene and chlorine. These monomers are then polymerized, often using a suspension or emulsion polymerization process, to form the vinyl chloride polymer resin. The resulting polymer can be further processed, such as through extrusion or injection molding, to create the desired final products.

The main inputs required for the production of vinyl chloride polymers include the raw materials of ethylene and chlorine, as well as various additives and catalysts used in the polymerization process. Additionally, specialized machinery and equipment, such as reactors, extruders, and molding machines, are essential for the efficient and large-scale production of these polymers.

The primary outputs of HS code 391530 are vinyl chloride polymer resins, which can be used to manufacture a wide range of products. These resins are often consumed by industries such as 392010 Plates, sheets, film, foil and strip, of polymers of vinyl chloride, 392020 Doors, windows and their frames and thresholds for doors, of polymers of vinyl chloride, and 392030 Fittings for furniture, coachwork or the like, of polymers of vinyl chloride, among others. The waste, parings, and scrap generated during the production and processing of vinyl chloride polymers can also be recycled and reused in various applications.
