Acrylonitrile butadiene rubber is a copolymer of acrylonitrile butadiene and butadiene. It has excellent resistance to petroleum and non-polar solvents, and
has good mechanical properties. The specific properties are mainly determined by the content of acrylonitrile. The content of acrylonitrile content higher
than 50% has strong resistance to mineral oil and fuel oil, but its elasticity and permanent compression deformation become worse at low temperature. Low
acrylonitrile butadiene acrylonitrile rubber has good low temperature resistance, but it reduces oil resistance at high temperature.
Advantages:
1. Good oil resistance, water resistance, resistance to solvent / high pressure oil.
2. Good compressive properties, wear resistance and tensile properties.
3. Rubber parts for making fuel tanks and lubricants.
4. It is used for hydraulic oil, gasoline, water, silicon grease, silicone oil, two ester lubricating oil and glycol system.
5. Rubber parts used in hydraulic fluids and other media
Disadvantages:
1. It is not suitable for polar solvents such as ketones, ozone, nitro hydrocarbons, MEK and chloroform.
2. Intolerance to ozone, weather resistance and heat resistance.
Package Include:
Seal Ring x 10
