What is NBR?
NBR is an abbreviation for nitrile butadiene rubber, which is also called nitrile rubber. Well-known trade names for this elastomer are Nitrile® / Perbunan® and BUNA-N®. NBR is the most widely used elastomer in the sealing industry. This material is mainly used for applications where fuel and oil come into contact with the O-ring, but also for many other types of applications.
What is NBR used for?
- Seals
- O-rings
- Gaskets
- Pipe and Cable Covers
The advantages of NBR O-rings:
- 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 -40 °C tot + 130 °C (-30 °F tot + 250 °F)
The disadvantages of O-rings 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
