Polycrystalline Mullite with excellent chemical stability

Polycrystalline mullite fiber (PMF) is the latest ultra-light high-temperature refractory fiber in China and abroad. It is a type of Al2O3-SiO2 ceramic fiber. Its operating temperature is 1500-1700℃, which is 200-400℃ higher than that of glass fiber. Polycrystalline mullite fiber production technology.

Product Features
• Low thermal conductivity
• Low heat capacity
• Thermal shock resistance
• Excellent chemical stability
• Free of binders and corrosive substances
• Loose and flexible at high temperatures with good elasticity

Application:

Polycrystalline mullite fiber products can be used as insulation materials in high-temperature thermal equipment below 1600℃ for a long time, such as silicon carbide electric furnaces, molybdenum silicide electric furnaces, various steel heating furnaces, mechanical forging furnaces, etc., which can significantly improve the thermal efficiency of equipment, greatly save energy, improve productivity, and improve product quality.
It can be used for insulation of various high-temperature industrial kilns; ceramic kilns; mechanical and metallurgical heating furnaces; hot surface linings of heat treatment furnaces and other industrial kilns; high-temperature fire and flame barriers; kiln doors, kiln cars, expansion joints and other insulation materials; glass kiln insulation.
