NBR(nitrile butadiene rubber)

*Service Temperature

For NBR the service temperature can be designed from -55 C to 100 C or up to 130 C depending on differenacrylonitrile

content and formula.

 

*Application

NBR compounds have excellent resistance to abrasion, non-polar oils and solvent, water and permeation (higher acrylonitrile

content will be better). NBR also can be used in conditions of dilute acids, alkalis and salt solution at low temperatures.

Following elastomers can be use in O ring :

* Aflas® or Kalrez®(FFKM)
* Acrylate Rubber(ACM)
* Butyl Rubber(IIR)
* Ethylene-propylene (EPR, EPDM)
* Ethylene Acrylate Rubber(AEM)
* Fluorocarbon (FKM/FPM/FKM)
* Fluorosilicone(FVMQ)
* Hydrogenated Nitrile (HNBR)
* Neoprene Rubber(CR)
* Nitrile Rubber (Buna-N/NBR)
* Natural Rubber(NR)
* Polyurethane(PU)
* Silicone Rubber
* Styrene-butadiene Rubber (SBR)

Different elastomers have different compatibility with various chemical elements and their characteristics. See the

table below for more material knowledge to order the most cost-effective o-rings from us.
