Amino-resins; melamine resins, in primary forms

HS v2017 Code: 390920

About amino-resins; melamine resins, in primary forms

HS code 390920 covers amino-resins and melamine resins in their primary forms. These synthetic thermosetting plastics are widely used in a variety of industries, including construction, furniture, and automotive manufacturing. They are valued for their durability, heat resistance, and excellent insulating properties, making them essential materials in many modern products and applications.

Production process

Amino-resins and melamine resins are typically produced through a polycondensation process. This involves the reaction of formaldehyde with amino compounds, such as urea or melamine, to form long-chain polymer molecules. The resulting resin is then further processed, often through compression molding or extrusion, to create the desired primary forms, such as sheets, rods, or granules.

Production inputs

The main raw materials required for the production of amino-resins and melamine resins are formaldehyde, urea, and melamine. Specialized machinery, such as reactors, extruders, and molding equipment, is also essential for the manufacturing process. Additionally, various additives, such as fillers, plasticizers, and stabilizers, may be incorporated to enhance the properties of the final products.

Production outputs

The primary outputs of HS code 390920 are amino-resin and melamine resin products in their basic forms, such as sheets, rods, and granules. These materials are then further processed and incorporated into a wide range of end-products, including 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392020 Plates, sheets, film, foil and strip, of plastics, cellular, and 392190 Other plates, sheets, film, foil and strip, of plastics, n.e.s.. The versatility of these resins makes them essential components in the manufacturing of furniture, construction materials, electrical and electronic devices, and automotive parts.
