Anti-oxidising preparations and other compound stabilisers; for rubber or plastics, other than mixtures of oligomers of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ)

HS code 381239 covers a range of anti-oxidising preparations and other compound stabilisers used in the rubber and plastics industries. These additives play a crucial role in enhancing the durability, longevity, and performance of a wide variety of products, from automotive components to consumer goods. As a key part of the broader chemicals and materials sector, this industry is essential for supporting the growth and innovation of numerous downstream industries.

The production of anti-oxidising preparations and compound stabilisers typically involves the synthesis of organic compounds, often through chemical reactions and blending processes. Manufacturers may use a range of techniques, such as distillation, filtration, and mixing, to create the desired formulations and ensure consistent quality. The specific production methods can vary depending on the target application and the unique properties required for each type of additive.

The main inputs for this industry include a variety of raw materials, such as phenols, amines, and other organic compounds, as well as solvents, catalysts, and other processing aids. Manufacturers also rely on specialized equipment, such as reactors, distillation columns, and mixing tanks, to facilitate the production of these stabilising additives. Additionally, the industry may consume outputs from related chemical sectors, such as 290230 Aromatic monohydric alcohols and 290420 Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives.

The primary outputs of this industry are the anti-oxidising preparations and compound stabilisers, which are then consumed by a range of downstream industries, particularly the rubber and plastics manufacturing sectors. These additives help to improve the resistance of materials to degradation, oxidation, and other forms of deterioration, thereby extending the lifespan and performance of a wide variety of products. Some of the key industries that may consume the outputs of HS code 381239 include 400211 (Styrene-butadiene rubber (SBR); carboxylated styrene-butadiene rubber (XSBR)) and 392010 Plates, sheets, film, foil and strip, of polymers of ethylene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
