Alumina Fiber MAFTEC® OBM (Organic Bound MAT)
MAFTEC® is polycrystalline alumina fiber. It is produced by an unique needle punching method.
MAFTEC® is used as substrate support mat for automobile´s catalytic converters and DPFs.
MAFTEC® will maintain its resiliency and durability against erosion for extended periods of time at temperatures over 800°C (1500°F).
