Nitril rubber, also known by the names Buna-N, Perbunan and NBR, is a synthetic rubber volumes of acrylic nitrile (ACN) and Butadia. 

Nitril butadie rubber is a family of unsaturated copolymers of 2-propennitril and various butadien monuments (1.2 and 1.3-butadia). The physical and chemical properties vary depending on the nitrile composition of the polymer, but this form of synthetic rubber is normally still resistant to oils, fuels and other chemicals. The more nitril in the polymer, the higher the oil resistance but lower flexibility in the material. 

The rubber is used in the vehicle and aviation industry for the manufacture of fuel and oil hoses, Seals and gaskets. Nitril rubber durability to temperatures in the area -40 ° C - +100 ° C makes it an ideal sealing material in the aviation industry. 

Nitril rubber has better resistance to oils and acids than natural rubber, but lower strength and flexibility.

Area of ​​use: hydraulic oils, vegetable oils, animal oils, acetylene, water, air, alcohol, fuels and many other media.
NBR 70 Shore A Standard Material, NBR 90 Shore A is used in High Press Hydraulic Applications

O-Rings In NBR, low -setting value and very good resistance to liquids such as mineral oils,
Vegetable oils, fats. Water glycol mixtures at temperatures not exceeding 60 ° C.

The working temperature of a standard material is from -25 ° C to +100 ° C with tops up to 120 ° C.
NBR materials (polar version) for applications at lower temperatures are also available but are only manufactured after orders.

Properties
+ Wide temperature range
+ High and constant friction
+ High abrasion resistance, even at high temperature
+ Very good dynamic properties
+ Permanent against oils and acids
+ Extraordinary antistatic properties of black nitrile rubber (with kim smoke)
-becomes brittle by UV light and ozone (limited outdoor use)
- Work and energy-intensive representation (vulcanization)
