The high strength and outstanding resistance of Nitrile Butadiene Rubber against water, alcohols, heat, abrasions, and petroleum compounds like gasoline, diesel oil, and other fuels over a wide temperature range are also noteworthy. Nitrile Butadiene Rubber offers a wide range of uses due to all these characteristics, including hose, belting and cable, O-rings and seals, sponges, gloves, expanded foams, footwear, latex applications, molded and extruded items, adhesives, and sealants.
Nitrile Butadiene Rubber is also utilized as an impact modifier for PVC and ABS in powder form.. The expansion of numerous end-use industries, including those in the automotive, aerospace, construction, pharmaceutical, oil and gas, and machinery sectors, is driving up demand for nitrile butadiene rubber. Nitrile rubber (NBR), commonly known as nitrile-butadiene rubber, is a synthetic rubber that resists oil and is made from a copolymer of butadiene and acrylonitrile. Fuel hoses, gaskets, rollers, and other goods requiring oil resistance are its primary uses.
Nitrile Butadiene Rubber is produced by copolymerizing acrylonitrile and butadiene in a process known as emulsion polymerization. The two monomers are mixed together in a reactor, along with water, emulsifiers, and other additives. The mixture is then heated, and a catalyst is added to initiate the polymerization reaction. As the reaction proceeds, the polymer particles grow and eventually form a latex that can be coagulated and dried to form a solid rubber.
The properties of the resulting NBR depend on the ratio of acrylonitrile to butadiene in the starting mixture. Higher levels of acrylonitrile result in a polymer with improved chemical resistance but reduced elasticity, while higher levels of butadiene result in a polymer with improved elasticity but reduced chemical resistance. The specific formulation used depends on the intended application of the NBR.
