Approaching nitrile rubber

The Nitrile Butadiene Rubber（NBR） has an elongation of up to 300% and a tensile strength of more than 10 N/mm. Nitrile rubber has good resistance to mineral oil, vegetable oil, benzene, gasoline, common dilute acid and alkali. However, the lip seal of the nitrile rubber cannot be used above 80 ° C because at this temperature, the nitrile rubber is degraded under the stability of the solvent. The high elasticity of nitrile rubber makes it a raw material for the manufacture of disposable laboratory gloves for laboratory use. Nitrile rubber is also more resistant to grease and acid corrosion than natural rubber. Although the elasticity and strength are lower than that of natural rubber, the nitrile rubber has several times more corrosion resistance than natural rubber.

Nitrile rubber is used in the manufacture of oil conveying hoses and flame retardant conveyor belts. Secondly, it is used in the automotive industry for sealing devices, as well as oil-resistant gaskets, gaskets, bushings, flexible packaging, soft hoses, printing and dyeing rollers, cable gluing materials, and nuclear gloves for the manufacture of protective gloves. Nitrile rubber has a strong temperature adaptability and can work normally in the temperature range of −40 to 108 °C. This property makes nitrile rubber widely used in the aerospace industry. Nitrile rubber can also be cast into a variety of products.
