Use NBR safely at temperatures down to -65 °C

Innovative low-temperature mixture also for various manufacturing processes

NBR is one of the most commonly used materials, with a property profile that has proven itself in many applications over decades. However, there are limits, for example in low-temperature applications. Here, a new compound opens up new perspectives.

NBR is known under various trade names such as Perbunan NT, Europrene®, Nipol N® Breon® or also under the old name Buna N. The material was developed around 1930 by Eduard Tschunkur, Erich Konrad and Helmut Kleiner at I. G. Farben.

Due to its favourable material price basis and chemical and mechanical properties, NBR is the standard material for numerous applications in hydraulics and pneumatics, among others. Compared to many other elastomers, NBR compounds are superior in terms of compression set, tear and abrasion resistance. NBR is also resistant to oil-based hydraulic fluids, greases, animal and vegetable oils, flame retardants (HFA, HFB, HFC), lubricants, water and air. In addition, there are special mixtures for use at extremely low temperatures, with corresponding stabilisation with regard to the ageing of the material or use in contact with special media. The application temperature range of common standard compounds is approx. -30 °C to + 100 °C continuous temperature, up to +120 °C for short periods.
