Advantages of ceramic insert ring :

1. abrasion-resistant formulations, dry-pressed molding.

Ceramic Insert Ring Application:
1. Industrial Insulating, Sealing and protecting materials
2. Electric and thermal insulation materials for electric industryInsulation materials for instrument-equipment
3. Insulating materials for motor industry
4. Filling materials for expansion slot
5. Isolating materials as the sinter resistance
6. Sealing gasket for molten metal


Ceramic Insert Ring Advantage:
1. Low thermal conductivity
2. Low thermal capacity
3. Resistance to thermal shock
4. Does not asbe stos, excellent corrosion resistance, does not react with modern aluminum
5. Excellent electric isolation and sound insulation
6. Strong but pliable in texture, highly pressure resistance.

We custom as per your size, if you have the drawings, it will be better for us to work out the cost.
