Ion-exchangers; based on polymers of heading no. 3901 to 3913, in primary forms
HS v2022 Code: 3914
About ion-exchangers; based on polymers of heading no. 3901 to 3913, in primary forms
HS code 3914 covers ion-exchangers, which are materials used to remove specific ions from solutions. These ion-exchangers are typically based on polymers from HS codes 3901 Polymers of ethylene, in primary forms to 3913 Polymers and resins, modified, not elsewhere specified or included, in primary forms. Ion-exchangers play a crucial role in water treatment, chemical processing, and various other industrial applications, making them an important component of the broader chemical industry.
Production process
Ion-exchangers are produced through polymerization and chemical modification processes. The base polymers are first synthesized, then functionalized with ionic groups to enable the ion-exchange capability. Common production methods include suspension polymerization, emulsion polymerization, and graft polymerization. The resulting ion-exchange resins are then processed into various physical forms, such as beads, membranes, or fibers, to suit the specific application requirements.
Production inputs
The main inputs for the production of ion-exchangers include the base polymer resins, such as polystyrene, polyacrylates, or polyvinylpyridine, as well as various chemical reagents for the functionalization process. Specialized equipment, such as polymerization reactors, drying systems, and particle size control mechanisms, are also essential for the manufacturing of ion-exchange materials.
Production outputs
Ion-exchangers produced under HS code 3914 are used in a wide range of applications, including water purification, hydrometallurgy, pharmaceutical processing, and nuclear waste treatment. The output of this industry is often consumed by industries covered under other HS codes, such as 2845 Isotopes other than those of heading 2844; compounds, inorganic or organic, of such isotopes, whether or not chemically defined, 2901 Acyclic hydrocarbons, and 2903 Halogenated derivatives of hydrocarbons.
