Paraformaldehyde

HS v2017 Code: 291260

About paraformaldehyde

HS code 291260 covers paraformaldehyde, a vital chemical compound used in a wide range of industries. As a polymer of formaldehyde, paraformaldehyde is an important raw material for the production of various resins, adhesives, and disinfectants. Its versatility and widespread applications make it a crucial component in the global chemical industry, contributing to the manufacturing of numerous consumer and industrial products.

Production process

Paraformaldehyde is typically produced through the polymerization of formaldehyde. This process involves the controlled condensation of formaldehyde molecules, resulting in the formation of a solid, white, crystalline material. The specific production techniques may vary, but often include steps such as the controlled heating and cooling of formaldehyde solutions, the use of catalysts, and the careful management of reaction conditions to achieve the desired polymer structure and properties.

Production inputs

The main inputs required for the production of paraformaldehyde include formaldehyde, which serves as the primary raw material, as well as various catalysts, solvents, and other additives that may be used to optimize the polymerization process. Additionally, specialized equipment, such as reactors, distillation columns, and drying systems, are necessary to facilitate the manufacturing of paraformaldehyde on an industrial scale.

Production outputs

Paraformaldehyde is a versatile chemical that finds applications in a wide range of industries. Its primary outputs are used in the production of 291211 (Methanal (formaldehyde)), resins, adhesives, and disinfectants. These products are then consumed by various downstream industries, including 392010 Plastic packing goods, 330499 Other beauty or make-up preparations, and 330610 Toothpaste, among others.
