O-RING
O-ring refers to a circular sealing element, usually made of rubber or plastic materials, used to prevent liquid or gas leakage. It is widely used in various industrial and mechanical equipment, such as automobiles, aerospace, medical equipment, etc.
Introduction to Rubber Materials
1/Nitrile rubber NBR
A. Advantages of Nitrile Rubber NBR
Has good characteristics of oil resistance, water resistance, solvent resistance, and resistance to high-pressure oil.
Has good compression deflection, wear resistance, and elongation.
B. Disadvantages of nitrile rubber NBR
Not suitable for use in polar solvents such as ketones, ozone, nitrohydrocarbons, chloroform, etc.
