Nitrile Rubber

Nitrile (NBR) rubber - Butadiene Acrylonitrile formula

Nitrile rubber is a copolymer of butadiene and acrylonitrile.

Resistant to heat, petroleum based oils and fuels over wide range of temperatures

Specific property requirements are satisfied by adjusting the proportion of each polymer used. A higher acrylonitrile content increases resistance to heat, petroleum base oils and fuels but decreases flexibility in low temperatures. Nitrile rubber’s petroleum resistance combined with its ability to be compounded for service over a wide range of temperatures make nitrile rubber one of the most widely used elastomers in the seal industry. Nitrile rubber exhibits excellent compression set resistance and good tear and abrasion resistance.

Not resistant to ozone, weather or heating ageing

Nitrile rubber is not suitable for applications requiring ozone, weather or heat aging resistance.

Used for fuel and oil handling hoses, seals and grommets

Nitrile rubber is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals and grommets. It is also used to create molded goods, footwear, adhesives, sealants, sponge, expanded foams and floor mats. Its resilience or snap makes nitrile rubber a useful material for disposable lab, cleaning, and examination gloves.
