Nitrile – NBR / XNBR

Nitrile (also referred to as Buna N), is known for its oil/fuel resistance and is generally compounded with reference to its “ACN” content (Low/Medium/High). Increasing the ACN improves oil resistance but impairs low temperature flexibility. It has found use in a broad range of industries with products that include hoses, ‘o’ rings, gaskets, rolls and tank linings.

Good oil/fuel resistance.
Wide temperature range from below -40°C/-40°F to above +100°C/212°F
Good mechanical properties
