Product description

The high density ceramic fiber board is a lightweight, flexible refractory fiber insulation material, which is processed from a combination of high-purity refractory oxides and organic binders. Ceramic fiber vacuum forming felt not only has the excellent properties of bulk ceramic fiber cotton, but also has good strength and elasticity. It is a multi-functional product.

Application of high density ceramic fiber board

1. Kiln backing insulation in petrochemical, metallurgy, ceramics and glass industries;
2. Backing insulation for non-ferrous metal industry;
3. High temperature reaction and heating equipment backing insulation

Advantages of high density ceramic fiber board

Standardized production workshop:We have sufficient production capacity for large-volume orders and can customize various refractory products.

Sufficient stock:The large warehouse has sufficient supply to meet your various requirements and save your time
