About polyurethanes; in primary forms

HS code 390950 covers the classification of polyurethanes in their primary forms. Polyurethanes are a versatile class of polymers that have a wide range of applications across various industries, including construction, automotive, furniture, and consumer goods. As a key component in the production of many essential products, the polyurethanes industry plays a vital role in the global economy.

Production process

Polyurethanes are typically produced through a chemical reaction between a polyol and an isocyanate. This process involves the controlled mixing and reaction of these two key ingredients, often with the addition of catalysts and other additives, to create the desired polyurethane polymer. The specific production techniques can vary depending on the intended application and the desired properties of the final product.

Production inputs

The main inputs required for the production of polyurethanes include polyols, isocyanates, and various additives such as catalysts, surfactants, and flame retardants. These raw materials are sourced from the petrochemical industry and are subject to fluctuations in global commodity prices. In addition to these chemical inputs, the production of polyurethanes also requires specialized machinery and equipment to facilitate the mixing, reaction, and processing of the materials.

Production outputs

The primary outputs of the polyurethanes industry are a wide range of products, including foams, coatings, adhesives, and elastomers. These polyurethane-based materials are then consumed by various downstream industries, such as 940360 Furniture, 870321 Motor vehicles, and 392010 Plastic products. The versatility of polyurethanes allows them to be used in a diverse array of applications, making this industry an essential component of the broader manufacturing and construction sectors.
