Hot-sale Gootren Aluminum Silicate Felt


Aluminum silicate blanket/felt/roll

Item No.: GQ-ASF


Aluminum silicate, also known as ceramic fiber, 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.

Main Specifications

Density (kg/m3):   90-110

Thickness (mm): 15-50

Width (mm):     400, 600, 1200

Length (m):     as required

Can be classified into aluminum silicate fiber roll felt and aluminum silicate fiber flat felt according to application.

Product Characteristics

l  Low thermal conductivity, low thermal capacity

l  Excellent thermal insulation and deadening performances

l  Excellent thermal and chemical stability


l  Wall lining for industrial kilns, heating equipment and high temperature pipes.

l  Wall lining for chemical high temperature reactors and heaters.

l  Fire-proof and thermal insulation for high rise buildings.

l  Thermal insulation for eliminating stress in welded work pieces and irregular metal castings.

l  Thermal insulation for top cover of kiln doors and thermal insulation for glass melting furnace.
