In life, we may encounter nitrile oil-resistant hoses. But do you know about this nitrile rubber hose?
First, let me introduce the composition of nitrile rubber. Nitrile rubber is a mixture of acrylonitrile and butadiene. Therefore, it has excellent resistance to petroleum and non-polar solvents. At the same time, it also has good mechanical properties. These properties mainly depend on the content of acrylonitrile in the rubber. When the acrylonitrile content is higher than 50%, it has strong resistance to mineral oil and fuel. However, its elasticity and permanent compression deformation at low temperatures will deteriorate. Low-content acrylonitrile nitrile rubber has good low-temperature resistance. But it reduces the oil resistance at high temperatures.
Advantages:
Good oil resistance, water resistance, aging resistance and high-pressure oil resistance
Good compression deformation performance, wear resistance and tensile strength
Used to make rubber parts for fuel tanks and lubricating oil tanks
Disadvantages:
Not suitable for use in polar solvents, such as ketones and ozone
Not resistant to ozone and hot air aging
