Epoxide resins; in primary forms

HS v2017 Code: 390730

About epoxide resins; in primary forms

HS code 390730 covers epoxide resins, which are a type of thermosetting polymer widely used in a variety of industries. Epoxide resins are known for their excellent adhesive properties, chemical resistance, and thermal stability, making them essential materials in applications ranging from coatings and adhesives to composites and electronics. As a key component in many manufacturing processes, the epoxide resins industry plays a vital role in the broader economy, supporting the production of a wide range of consumer and industrial products.

Production process

Epoxide resins are typically produced through a polymerization process involving the reaction of epoxide compounds, such as epichlorohydrin, with other reagents like bisphenol A. The resulting polymer chains can then be further modified or combined with other materials to achieve desired properties. Manufacturers often use batch or continuous processes, depending on the scale and specific requirements of the final product.

Production inputs

The main inputs for the epoxide resins industry include epoxide compounds, curing agents (such as amines or anhydrides), and various additives like fillers, plasticizers, and flame retardants. Specialized equipment, such as reactors, mixers, and extrusion systems, are also essential for the production of epoxide resins. The industry relies on a robust supply chain of raw materials and machinery to meet the growing demand for these versatile materials.

Production outputs

Epoxide resins produced under HS code 390730 are used in a wide range of applications, including 390810 Epoxide resins in primary forms, 390950 Polyurethanes in primary forms, and 392010 Plates, sheets, film, foil and strip, of polymers of ethylene. These resins are often further processed and combined with other materials to create a variety of end products, such as coatings, adhesives, composites, and electrical insulation components.
