Features

NBR is a very commonly used material for O-rings because of its good mechanical properties, its resistance to lubricants and greases and its relatively low cost
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
