The origin of NBR

Nitrile-butadiene rubber (NBR) was developed by the chemical company ‘I.G. Farbenindusty’ from Germany between WWI and WWII. At first the material was called Buna-N® and was later renamed to Perbunan®. The material first came to market in the 30s and is nowadays the most used elastomer for standard seals like O-rings and other seals.

What is NBR?

NBR is an elastomer, which is a synthetic polymer obtained by the copolymerization of acrylonitrile and 1,3-butadiene. The characteristics are partly determined by the amount of acrylonitrile in the material and this varies from 18 to 50 percent. As the acrylonitrile increases, resistance to petroleum base oils and hydrocarbon fuels increases, but low temperature flexibility decreases and the rubber can become brittle.

What is NBR used for?

Seals
O-rings
Gaskets
Pipe and Cable Covers

The advantages of NBR

Resistant against oils, fats, hydrocarbons, diluted acids
Has good mechanical qualities and is wear-resistant
Good resistance to heat
It is powerful and elastic
It has a working temperature range of -35°C tot + 120°C (-30 ° F tot + 250 ° F)

The downside of NBR

It has limited resistance to weather and ozone conditions
Not well resistant to aromatic compounds, halogenated hydrocarbons, ketone brake fluids and strong acids
Must be kept out of direct sunlight
The working temperature range is limited in comparison to other materials
