Epoxide resins; in primary forms

HS v2022 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. This industry plays a crucial role in the broader chemical and manufacturing sectors, contributing to 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 groups with other reactive compounds, such as amines or anhydrides. The specific production techniques can vary, but often involve the use of catalysts, heat, and controlled reaction conditions to ensure the desired properties of the final product.

Production inputs

The main inputs required for the production of epoxide resins include epoxide-containing compounds (such as bisphenol A or epichlorohydrin), curing agents (such as amines or anhydrides), and various additives (such as fillers, plasticizers, or flame retardants) to modify the resin's properties. Additionally, specialized production equipment, such as reactors, mixers, and curing ovens, are essential for the manufacturing process.

Production outputs

Epoxide resins produced under HS code 390730 are used as key components in a wide range of products, including 390740 Epoxide resins, in primary forms, 390750 Alkyd resins, in primary forms, and 390760 Polyamides, in primary forms. These resins are further processed and incorporated into applications such as coatings, adhesives, composites, and electrical insulation materials, among others.
