China and South Korea are the leading exporters of Poly(acrylonitrile-co-butadiene), accounting for the largest share of global shipments, while the United States, Germany, and Mexico represent the top importing countries. Trade volumes remain concentrated among these key players, with consistent flows across North America, Asia, and Europe. Recent data indicates relative stability in export volumes from major Asian producers, though fluctuations in Poly(acrylonitrile-co-butadiene) prices have accompanied shifts in regional demand, particularly in automotive and textile end-use sectors.
Poly(acrylonitrile-co-butadiene) is a synthetic copolymer appearing as a white to off-white rubbery solid, typically supplied in pellet or crumb form; it is non-volatile, odorless, and lacks a sharp melting point due to its thermoplastic elastomeric nature. It is classified as a synthetic elastomer and belongs to the family of nitrile rubbers. Primarily used as an intermediate in the production of impact-modified engineering thermoplastics—especially acrylonitrile–butadiene–styrene (ABS) resins—it serves as the butadiene-rich phase that imparts toughness and impact resistance. Its main application areas include automotive components, consumer electronics housings, pipes and fittings, and general-purpose plastic products requiring enhanced mechanical durability.
Applications include fuel lines,hoses, automobile parts, structural adhesives, oil-resistantclothing or articles, gloves, and shoe soles and heels.Gloves made of nitrile rubber are comparable to neoprenegloves in their resistance to organic solvents; nitrile rubbergloves were superior in resistance to II-hexane and inferior inresistance to phenol. NBR is used for hoses, gaskets, andprotective clothing.
NBR is important for its high oil and temperature resistance.Flexibility at very low temperatures is obtained with loweracrylonitrile content: in turn, this sacrifices some oil resistance.Low-temperature flexibility for some applications canbe modified by plasticizers or blends. Additional propertiesinclude resistance to heat, abrasion, and water, as well asresistance to gas permeation. NBR is frequently plasticizedwith organic phosphate, phthalic ester, or dibenzyl ether.
