Advantage of alumina ceramic spacer gasket / alumina nitride spacer
1. Isostatic pressed.
2. Fire resistance.
3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. Zirconia and alumina ceramic material.
They are high corrosion and wear resistance and strong impact resistance and delivers 10 times longer working life than metal plunger. They give a longer life to the sealed packing material.
