Nitrile Rubber / NBR Rubber

The oil-resistant rubber material

Working Temperature Range:

High: 212°F / 100°C Low: -22°F / -30°C

Nitrile - NBR rubber is the ideal choice for any product that requires petroleum (oil or gas) resistance.  Nitrile / NBR can be formulated to have excellent abrasion resistance, tear strength, and compression set.  Nitrile / NBR is not a good choice for applications where it will be exposed to weather or ozone.

Advantages:

  • Excellent petroleum resistance
  • Good tear strength
  • Excellent abrasion resistance
Disadvantages:
  • Poor weather resistance
  • Moderate operating temperature range
