● 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.
