ISOWOOL WET FELT
Features
ISOWOOL BLANKET with inorganic binder of colloidal silica
Made from ISOWOOL 1260 BLANKET with an inorganic colloidal silica binder, it is delivered in a plastic bag. Its flexibility and moldability make it suitable for complex shapes. After drying, it hardens due to the binder, making it ideal for furnace surfaces requiring more solidity to withstand higher gas velocity.
1. Once air-dried, it becomes a lightweight insulator that can be sawed, cut, or sanded.
2. It is cut into shape using scissors or a cutter.
3. Though WET FELT has a bulk density of about 400 kg/m3 when dry, it is heavier during installation due to the aqueous binder. Thus, the standard size is 600 x 300 mm.
Typical Applications
1. Trough linings for conveying molten metals
2. Hot gas duct linings.
3. Furnace hot face lining in ceramic kiln, box furnace and petrochemical furnace, for high velocity and/or durable insulation.
4. Protection alloy hardware exposed to high temperatures.
