Features:
- Good chemical resistance to mineral oils and greases
- The physical and chemical resistance properties of NBR materials are determined by the acrylonitrile (ACN) content of the base polymer which can vary between 18 and 50%
- Low ACN content ensures good flexibility at low temperatures, but offers limited resistance to oils and fuels
- As the ACN content increases, the low temperature flexibility reduces and the resistance to oils and fuels improves
- Physical and chemical resistance properties of NBR materials are also affected by the cure system of the polymer
- Peroxide cured materials have improved physical properties, chemical resistance and thermal properties as compared to sulfur-donor-cured materials
- Standard grades of NBR are typically resistant to mineral oil-based lubricants and greases, many grades of hydraulic fluids, aliphatic hydrocarbons, silicone oils and greases and water to about 80 deg C
- NBR is generally not resistant to aromatic and chlorinated hydrocarbons, fuels with a high aromatic content, polar solvents, glycol based brake fluids and non-flammable hydraulic fluids (HFD)
- NBR also has low resistance to ozone, weathering and aging, but in many applications this has no negative effect
