● Features : 

NBR is a copolymer of acrylonitrile and butadiene, with excellent resistance to petroleum and non-polar solvents, and good mechanical properties. Specific performance mainly depends on the content of acrylene eye component, acrylene eye content is higher than 50% of those with strong resistance to mineral oil and fuel oil, but its elasticity at low temperatures, permanent compression deformation deterioration, low acrylene eye nitrile rubber has a good low-temperature resistance, but reduces the high temperature resistance to oil performance.

Advantages
1. good resistance to oil, water, solvents and high pressure oil.
2- Good compression permanent deformation properties, abrasion resistance and tensile properties
3-Used in the manufacture of rubber parts for fuel tanks and lubricating oil tanks
4-Rubber parts for use in petroleum-based hydraulic fluids, gasoline, water, silicone grease, silicone oil, diester lubricants, glycol-based hydraulic fluids and other fluid media

Disadvantages
1 Not suitable for use in polar solvents such as ketones, ozone, nitro hydrocarbons, MEK and chloroform.
2 Not resistant to ozone, weathering and heat aging.

Suitable media: - Aliphatic hydrocarbons (butyl)
1 Aliphatic hydrocarbons (butane, propane), engine oils, fuel oils, vegetable oils, mineral oils.
2- HFA, HFB, HFC hydraulic oils
3- Low concentration of acids, alkalis, salts and water at room temperature.
