Refractory Ceramic Fiber Wool Bulk

Aluminosilicate refractory fiber wool, the basic form of refractory fiber, is the fundamental material to produce a variety of fiber products.

Properties:
1. Excellent thermal stability
2. Low heat capacity and thermal conductivity
3. Nobinders and other erosives
4. Low slag shot content.

AppIications:
1. Raw material for refractory fiber board, blanket,
2. Expansion joint fillings.
3. Reinforcing materials for casting, mouldable and binder.
4. Precursors for engineered fiber material.
