Maftec®
Polycrystalline Alumina Fibers
MAFTEC® was developed in the 1980’s by Mitsubishi Plastics Inc., for long term, high or cyclic temperature operation. MAFTEC® “Polycrystalline Alumina Fibers”, exhibit excellent thermal stability, resiliency, erosion resistance and mechanical strength at temperatures to 1600°C – 2912°F.
MAFTEC® is a Mullite fiber. Mullite is a stable material that does not change molecularly through the temperature range, up until it melts (1850°C). The silica in MAFTEC® is contained within the structure of Mullite and is not allowed to form free silica. MAFTEC® fiber diameter averages 5 microns.
Advantages
- Extremely low shrinkage-1% at 1400°C-2552°F. 1 1/2% at 1600°C-2912°F
- Weight and thickness tolerances to ensure value
- Service temperature range-up to 1600°C-2912°continuous
- Higher Tensile Strength-maintaining lining integrity
- Total Thermal Shock Resistance
- Installed easily and quickly in all temperature environments
- Low, Low, Low shot content due to manufacturing technology
- Extreme Weight Reduction-lining densities of 8-10#/cu.ft. compared to monolithic of 150-160#/cu.ft.
- Resiliency Performance-to 1300°C
- 1% shrinkage at 1400°C
