Nitrile (NBR)
Nitrile or NBR stands for Nitrile-Butadiene-Rubber. The material is exceptionally good against hydraulic oils, motor oil and other oils typical for industry.
Nitrile is produced as a sheet material. The flat nitrile sheet is produced to die-cut and waterjet cut seals, gaskets, membranes and seal strips.
The raw material is also available as a ribbed rubber mat, for example in workbenches and shelves. Considering the resistance for oil and petroleum this material is suitable for workbenches at car-mechanics.
In difference to other, more cost-effective qualities of ribbed rubber materials, the NBR is more odorless and is better suited for shelves in stores compared to other rubbers.
The material may also be produced with a reinforcement inside the rubber sheet to increase durability and stability in the material. The Nitrile is then produced with a textile-inlay inside the sheet that limits the elasticity in the material.
Commonly seen products in molded and extruded NBR is O-rings, X-rings, hoses and extruded seal strips.
Other qualities of Nitrile, such as HNBR or Hydrated-NBR is that is retains better thermal properties with a peak temperature of up to 165°. HNBR can withstand more chemical substances than the traditional Nitrile and is therefore well suited in tougher environments.
HNBR can in some cases replace rubber-products in FKM/FPM for a more cost-effective gasket or seal.
Like other rubber qualities, the Nitrile may be obtained in many different shore-values which indicates the hardness of the material. The most common hardness we see is 65Sh.
