Feature of ceramic sealing ring 

1)  High hardness.

2)  High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is

widely used in areas where resistance to high temperatures is essential.

3) Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.

4) High electrical resistivity : Alumina is an electrically insulating material.

5)High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and

alkaline solutions.

6) Good chemical stability of alumina leads to high corrosion resistance.
 

Advantages of the ceramic seal rings
1. The sealing ring in the working pressure and a certain temperature range, should have good sealing performance, and with the increase of pressure can automatically improve the sealing performance.
2. The friction between the sealing ring device and the moving parts should be small and the friction coefficient should be stable.
3. The sealing ring has strong corrosion resistance, not easy to aging, long working life, good wear resistance, and can be automatically compensated to a certain extent after wear.
4. Simple structure, easy to use and maintain, so that the sealing ring has a longer life.
