Ceramic Fiber Blanket
Product Number:
The ceramic fiber blanket is made of special aluminum silicate ceramic long filament fiber using special double-sided needling technology. The double-sided needling technology significantly improves fiber interlacing degree, split resistance, tensile strength and surface flatness.
The ceramic fiber blanket contains zero organic bonding agent, ensuring excellent plasticity and stability in high-temperature and low-temperature operating conditions. Besides, it is spotlessly white in color and uniform in size, integrating fire resistance, thermal insulation and heat preservation. The insulation material can also remain satisfactory tensile strength, toughness and fiber structure when used in neutral gas and oxidizing gas for a long time.
Features
1. High tensile strength and low shrinkage
2. Great resiliency with low heat storage
3. Low thermal conductivity
4. Good sound absorption
Applications
The ceramic fiber blanket has an up to 950-1400 ℃ refractoriness, well applicable for high-temperature insulation and heat preservation in aerospace industry, steel industry and petrochemical industry, fire resistance and thermal insulation of military equipment and electric component, thermal insulation and heat preservation of wall lining and back lining of industrial kiln and heating equipment, high-temperature equipment, high-temperature pipeline. Besides, the ceramic fiber blanket can be used as the raw material of high-temperature spacer, module, collapse block, etc.
