Nitrile rubber is a butadiene-acrylonitrile copolymer also called NBR. It is renowned for its excellent resistance to petroleum products, fuels, aliphatic solvents, animal and vegetable oils and fats.
Advantages of nitrile rubber:
- Good resistance to oils, fuels, polar and aromatic solvents.
- High conductivity
- Good mechanical properties: resistance to tearing, abrasion, resilience,
- Temperature: -40°C to +100°C
Limits: Highly flammable, Low resistance to cold, aging, ozone, weathering
Example of nitrile applications:
- Gloves for the chemical industry
- Printing rollers
- Fuel tanks
Sectors of use of nitrile :
- Aviation industry
