Ceramic fiber board is a high-performance insulating product formed by ceramic fiber and adhesive in vacuum. It is flat, ceramic materials are evenly distributed, and has excellent heat insulation performance. Due to its low thermal conductivity and low heat storage, no inflation during heating can reduce energy cost and cycle time, and protect the refractory surface from thermal shock and chemical attack. Therefore, it is an ideal product for fire resistance, heat insulation and heat insulation.
Features
1.Low heat storage;
2.Resistant to Non-Ferrous Metals;
3.Excellent resistance to thermal shock and chemical attack;
4.Resists oxidation and reduction;
5.High mechanical strength at high temperature;
6.Can be machined, cut and shaped easily
7.High rigidity and light weight
