ceramic board for furnace lining
Meiyuan ceramic fiber board is made through automatic vacuum forming process. 24 hours continuously working, quickly drying. Meiyuan ceramic fiber board enjoys higher compressive strength, tidy surface and precise size, the thickness varies from 20mm to 100mm, which is easy for installation.
Low heat capacity, low thermal conductivity;
Non-brittle material, good elasticity;
High compressive strength;
Excellent wind-erosion resistance, long service life;
Excellent thermal stability and thermal shock resistance;
Continuous production, even fiber distribution and stable performance;
Good sound insulation;
Good anti-stripping properties;
Easily molded or cut, easy to install;
Accurate sizes and good flatness
