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 2912°F (1600°C).

MAFTEC™ is a Mullite fiber. Mullite is a stable material that does
not change molecularly through the temperature range, up until it
melts (3362°F (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 >>
