Maftec Blanket 1600

MAFTEC Blanket is made from pure mullite fibre only, needled on both sides, and contains no binder or other added constituent. It can be used at continuous operating temperatures up to 1600°C, under oxidizing, neutral or slightly gas-rich conditions, retaining its original toughness, strength and soft, fibrous structure after extended use at this temperature. MAFTEC Blanket is more resistant to acid and alkaline solutions and features exceptionally good thermal insulation characteristics.
FEATURES
- Due to its microcrystalline structure, MAFTEC mat is suitable for continuous operation at 1600°C
- Very low thermal conductivity
- Very low shrinkage at 1600°C
- Resistant to thermal shock
- MAFTEC Blanket is perfect for the manufacturing of modular blocks because it remains soft up to 1600°C
- Good sound absorption
- High strength makes it easy to handle and prevents tearing or punching around anchors
- Chemically stable and free of corrosive agents
- Low thermal conductivity
