Polycrystalline mullite fiber felt
The fiber felt is made of loose cotton and organic and inorganic binder, which is made by wet vacuum filter. The product has the elasticity, toughness and semi hard, no dust. Due to the use of a stable chemical properties of refractory fiber, and thus light weight, good thermal insulation effect, is a multi-purpose products, can meet the needs of many industries complex.
