Aluminum Silicate Felt

Aluminum Silicate Felt
Product Detailed
Low thermal conductivity Fire-proof Excellent chemical stability Density (kg/m3):80-130 Thickness (mm):15-50

Aluminum Silicate Felt




Aluminum silicate, also known as aluminum silicate, is a mixture of aluminum, silica, and oxygen that can be either a mineral, or combined with water to form a clay.


Production Technique

The common aluminum silicate blanket is manufactured with flint clay as main ingredient through melting, fiberizing (with addition of an adequate amount of cementing agent), solidification in solidification chamber and cutting. The whole process is fully PLC controlled and the product is formed in one continuous process.
