About rubber; synthetic, acrylonitrile-butadiene rubber (nbr), latex, in primary forms or in plates, sheets or strip

HS code 400251 covers the classification of synthetic acrylonitrile-butadiene rubber (NBR), a versatile and widely used type of rubber. NBR is known for its excellent resistance to oil, chemicals, and abrasion, making it a crucial material in various industries. This rubber compound is commonly used in the production of automotive parts, industrial hoses, seals, and other applications that require durable and flexible materials.

Production process

The production of NBR involves the copolymerization of acrylonitrile and butadiene monomers. This process is typically carried out in an emulsion or solution polymerization system, where the monomers are combined and polymerized under controlled temperature and pressure conditions. The resulting NBR polymer is then coagulated, dried, and processed into various forms, such as sheets, plates, or primary shapes, to meet the specific needs of different industries.

Production inputs

The main inputs required for the production of NBR include acrylonitrile and butadiene monomers, as well as various additives and processing aids. Specialized machinery, such as polymerization reactors, coagulation tanks, and drying equipment, are also essential for the manufacturing process. Additionally, energy sources, such as steam or electricity, are needed to power the production facilities.

Production outputs

The primary output of HS code 400251 is synthetic acrylonitrile-butadiene rubber (NBR) in various forms, including plates, sheets, and primary shapes. This material is widely used in the production of 400259 Rubber; synthetic, in primary forms or in plates, sheets or strip, not elsewhere specified or included, 401110 (Rubber; new pneumatic tyres, of a kind used on motor cars (including station wagons and racing cars)), and 401120 Rubber; new pneumatic tyres, of a kind used on buses or lorries as well as other rubber-based products across a range of industries.
