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

Properties

Excellent thermal stability

Low heat capacity and thermal conductivity

Excellent chemical stability

No binders and other erosives

Applications

Raw material for refractory fiber board, blanket, paper, fabric and shaped pieces.

Expansion joint fillings.

Reinforcing materials for castable, mouldable and binder

Precursors for engineered fiber material
