Oil-resistant rubber (NBR)

 

Acrylonitrile butadiene rubber, abbreviated as Nitrile is an elastomer invented in 1941 as the first oil-resistant rubber.

 

   The different types of oil-resistant rubber with higher acrylonitrile content have better oil-resistance, as the ones with lower content are more flexible and seal better at lower temperatures. The oil resistant rubber(nitrile) has average physical properties but good friction and abbrasive resistance.

    The gas tightness of the oil-resistant rubber is weak. Its ozone and electrical properties are also weak. The fire resistance of the oil-resistant rubber is weak and it’s not suitable for use with solvents. Some types of oil-resistant rubber can be produced with additive as PVC which enhance its resistance against aging, fire, oil products and ozone. The carboxylated types of the nitrile rubber as (XNBR) have better physical properties and better resistance at higher temperatures.

    There are also additive for use of the oil-resistant rubber with drink water with approval from (WRC/WRAS), as well as mixtures for use in the food and pharmaceutical industry.

   “SENY” LTD offers sheet material from oil-resistant rubber with width 1200 mm. We offer different thicknesses of the material from 1 mm up to 15 mm. In our facilities we have CNC plotter which allows us to cut precisely the needed product, even in complicated configurations and design from your our our drawings.

We can cut on request diaphragms, gaskets, deliver hoses, o-rings, seals etc.
