Thermal Insulation Alumina Ceramic Gasket with Coil Heat Resistant
Key words : Ceramic Gasket
1. 99 alumina,abrasion-resistant formulations, dry-pressed molding.
2. The chemical stability is better, high temperature
resistant,abrasion resistant and corrosion resistant.
3. The ceramic body is compact, and the mechanical strength is
high.
4. OD tolerance≤±0.02mm, ID tolerance≤±0.1mm,High
tolerance≤±0.05mm, Parallelism≤0.02mm.
5. Plane mirror-polished,the surface without pores,without
miscellaneous points,without scratches and cracks.
Ceramic Gasket 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
CeramicGasket 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.
