Specifications
Polycrystalline Mullite Ceramic Fiber Board (PMF) is a novel super-light high-temperature refractory fiber in the world, one of the whole Al2O2siO2 system ceramic fibers, with use
temperature of 1800 degrees to 1700 degrees, 200 degrees to 300 degrees higher that that of fiber glass. Polycrystalline mullite fiber (PMF), polycrystalline alumina fiber is currently at home and
abroad the latest ultra-lightweight high-temperature fire-resistant fiber, the whole system Al2O3-SiO2 ceramic fibers in two different products, It can be widely used in metallurgy, machinery,
electronics, ceramics, chemicals, aerospace and other high-temperature industrial furnaces and other thermal equipment, lined with insulation. In order to achieve energy efficiency increase, extend
furnace life, the purpose of improving the working environment. Appearance white, smooth, soft, flexible, just like cotton.
Application
Polycrystalline Mullite Ceramic Fiber Board Characteristic:
It is characterized in white appearance, smoothness, softness and elasticity, just like pledget. PMF is a polycrystalline mullite fiber in the existing form of mullite crystalling
phase, with a unique structure, complicated manufacturing process and high technical content.
1. High temperature stability to 1600-1800C
2. Ideal for use as furnace insulation in sintering, heat treating and chemical thermal process systems
3. Non-Flammable
4. Excellent thermal shock resistance
5. Resistance to most chemical attack; it has excellent stability in acid metal slags and is insoluble in most acids
6. Resistance to oxidation and attack by furnace atmospheres
7. Resistance to abrasion
8. Good electrical resistivity
9. Excellent thermal stability
10. Can be used as insulation packing in furnace spaces and around furnace sight tubes & ports
11. Fill in expansion joints and masonry cracks inside of furnaces.
