Extruded rubber profile in Nitrile
The NBR (acrylonitrile butadiene copolymer) is used for most gasketing applications for conventional fluids. The NBR standard used is the best compromise between resistance to oils and hydrocarbons, flexibility and mechanical strength. It gives a good to excellent impermeability to air and gases. Among the characteristics of chemical resistance NBR has a good resistance to oils, hydrocarbons or gases and in general to mineral, vegetable and animal fats.
Print Product Summary

Good resistance to oil and gasoline

Nitrile has very good oil and gasoline resistance, permeability, and heat and abrasion resistance.  Its resistance to alkalis and acids all increase as the nitrile content of the compound increases.

Nitrile must be specially compounded for resistance to ozone, sunlight and natural aging, and has poor resistance to oxygenated solvents.  Nitrile is superior to neoprene in oils and solvent resistance, but is not recommended for applications where it is exposed to severe weathering.

Nitrile’s service temperature ranges from -30 degrees F to 375 degrees F.
