Nitrile rubber

  1. 1.  Polymeric mixture of butadiene andacrylonitrile in the respective ratio 2:1. Ratios can be varied to change physicalproperties...higher levels of acrylonitrileyield low temperature flexibility, andincrease compound hardness Highly polar elastomer (large andreversible elsatic deformation)
  2. 2.   Excellent Good Fair PoorTensile strength •    Elongation   •    Low temperature flexibility   •    Compression Set   •    Tear resistance   •    Abrasion resistance •      Flame resistance       •Gas permeability   •    
  3. 3.   Excellent Good Fair PoorWater •      Petroleum oil •      Silicone lubricants •      Dilute acids   •    Dilute alkalis   •    Hydraulic fluids   •    Transmission fluid   •    Steam     •  Ozone       •Weather       •Ketones       •Strong acids       •Brake fluid       •
  4. 4.  Vibration Control ofhorizontal forces up to125 tons O Rings, gaskets,sealants, grommets andtubing pads Frequently used inautomotive airconditioning systemsemploying R-134arefrigerants
  5. 5.  Nitrile should not be exposed to› direct sunlight› moderate to high levels of atmosphericozone› oxygen Must be used in a closed system
  6. 6.  Nitrile acceptsantidegradants, whichimprove theaforementionedproperties› PVC (polyvinyl chloride)› Hydrogenation
  7. 7.  High tensile strength Low permanent set Good abrasion resistance High elasticity Stability toward thermal ageing Better properties at low temperatures
  8. 8.  Nitrile rubber is hydrogenated in solutionusing precious metal catalysts Carbon-carbon bonds are converted tomore stable single bonds (controlsdifferent states) Can be crosslinked using sulphur andperoxide cure systems
  9. 9. Nitrile 1/32” thick $14.80 persquare yard ¼” thick $72.20 persquare yardHydrogenated Nitrile 2 to 3 times moreexpensive than theconventionalpolychloroprene usednow New features will allowit to last 5.5 timeslonger
