Polycrystalline Mullite Fiber Blanket
Polycrystalline Mullite Fiber Blanket, also known as PCW blanket or polycrystalline fiber blanket, is a high-performance refractory insulation material designed for ultra-high-temperature industrial applications. Made from high-purity polycrystalline mullite fibers, it offers excellent high-temperature stability, low thermal conductivity, low linear shrinkage and good thermal shock resistance.
Mindelun supplies Polycrystalline Mullite Fiber insulation for industrial furnaces, kilns, heat treatment equipment, petrochemical furnaces, steel plants, aluminum furnaces, glass furnaces and other high-temperature thermal systems.
Key Features of Polycrystalline Mullite Fiber Blanket
- Ultra-high temperature resistance for demanding industrial insulation applications
- Low thermal conductivity to reduce heat loss and improve energy efficiency
- Low linear shrinkage for better dimensional stability during high-temperature operation
- Excellent thermal shock resistance for repeated heating and cooling cycles
- Lightweight and flexible for easy cutting, handling and installation
- Good chemical stability in demanding industrial environments
- Low heat storage for faster heating and cooling of thermal equipment
Applications
Polycrystalline Mullite Fiber Blanket is widely used as high-temperature insulation in:
- Steel reheating and heat treatment furnaces
- Aluminum melting and holding furnaces
- Petrochemical and reforming furnaces
- Glass furnaces
- Ceramic and tunnel kilns
- High-temperature electric furnaces
- Furnace doors, expansion joints and thermal seals
- Backup insulation and thermal protection systems
For applications requiring rigid insulation, Mindelun also supplies Polycrystalline Mullite Fiber Board and other PCW insulation products.
