Butadiene and acrylonitrile, like many SBRs, are made by emulsion polymerization. However, depending on the required properties, the amount of acrylonitrile varies from 20 to 50%. As the amount of nitrile increases, the resistance to hydrocarbons, solvents, abrasion and gas penetration increases. Reducing the amount of nitrile increases the properties at low temperatures and volatility. NBR rubbers are resistant to oils, solvents, water, salts, aliphatic compounds, soaps and most foods. These materials work continuously at a temperature of 120 ° C in the presence of air and at a temperature of 150 ° C in the oil environment.
The most important features of NBR anti-oil rubber (NBR) can be mentioned several of them: resistance to traction and wear, corrosion resistance of various industrial hot oils, very good flexibility, resistance to solvents Industrial, water, salts, gas penetration resistance, electricity insulation, ozone resistance and radiation hazards such as ultraviolet and dozens of other features that will help you use the most suitable product for your industry . The most important uses of NBR oil-resistant rubber are:
Application in aerospace industry, power plant and petrochemical industries; For example: Application in seals and fuel hoses
Suitable for use in fuel pumps as well as fuel tanks
Suitable for use in the production of safety shoes and safety gloves
