Product Details
Ceramic Fiber Board is manufactured in a wet forming process using ceramic fiber bulk and binders. It is designed for insulation applications experiencing vibration, mechanical stress and erosive forces. Ceramic fiber board can reduce engergy costs and cycling times due to high insulating capability, as well as serving to protect refractory surfaces from themal thock and chemical attack.
Features
- Excellent thermal shock resistance
- Can be machined, cut and shaped easily
- High rigidity and light weight
- Low thermal conductivity
- Low heat storage
Applications
Ceramic Fiber Board has the following applications:
- Furnace hot face lining in petrochemical furnace
- Furnace hot face lining in ceramic kiln
- Board over blanket hot face lining
- Back-up insulation to brick & castable
- Expansion joints
