Materials technology: NBR [nitrile rubber]
Nitrile rubber is widely used for fuel and oil seals and grommets in the automotive industry. Its −40°C - +108°C temperature range is ideal for aeronautical applications:
- resistant to attack from mineral oils, petroleum solvents
- fair resistance to heat and ageing
- relatively poor cold resistance.
