Nitrile butadiene rubber (NBR)

Nitrile butadiene rubber (NBR) is obtained by an emulsion polymerization of acrylonitrile (ACN) and butadiene. NBR products can be formulated with excellent abrasion features and resistance against a wide variety of oils, fuels and chemicals, e.g. mineral oils and greases, solvents, hydraulic oils, vegetable and animal fats.


Physical and chemical properties of final product can be controlled by selecting appropriate grades of NBR. Based on their versatility and excellent performance/cost ratio, NBR provides advantages to function well in a wide variety of automotive and industrial applications.


Nitrile-butadiene rubber is one of the rubbers with double bonds in its chemical matrix. Hence it is also used as an adhesive base material for solvent-based adhesives and dispersion adhesives.




Nitrile butadiene rubber (NBR) is used in fuel and oil handling hoses, floor mats, adhesives, plastic modifications, printing rolls, roll covers, conveyor belts, hydraulic hoses, off-road equipment, seals for several kinds of plumbing and appliance applications.
