**********************************************************

NBR is the most common standard material because of its good mechanical properties and resistance to mineral oil-based lubricants and greases. Good resistance to fuels is usually possible only with special compounds.

Its properties are mainly determined by the acrylonitrile content (ACN between 18% and 50%). A low ACN content ensures good flexibility at low temperatures, but offers limited resistance to oils and fuels; as the ACN content increases, flexibility at low temperatures decreases and resistance to oils and fuels improves.The standard NBR material offers an average ACN content to suit a wide range of applications with balanced properties. It has good mechanical technological values such as high abrasion resistance, as well as good resistance to mineral oil-based lubricants and greases, hydraulic oils H, H-L, H-LP, non-inflammable hydraulic fluids HFA, HFB, HFC, aliphatic hydrocarbons, silicone oil and greases and water to approx. +80°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-inflammable hydraulic fluids HFD. It has a low resistance to ozone, weather and ageing, but in most applications, e.g. when the material is wetted with oil, this has no negative effect.
