Aluminum Silicate Refractory Fiber Felt for furnace liner

Specifications

1.Excellent thermal stability
2.Excellent chemistry quality
3.Resistance to burning
4.Low thermal conductivity

High quality Aluminum Silicate Refractory Fiber Felt

 

SUNRISE CERAMIC FIBRE BLANKET is made of special ceramic long-fiber that is produced by the melting of very pure raw materials in double surface needing process without binders and with good stability in a large range of temperature. The process of double surface needling increases interweaving and tensile strength

 

Characteristic

 Non-combustible

Can withstand temperature up to 2600^oF

Low density and low thermal conductivity

Shorter heat up and cool down time

Resilience and resistance to thermal shock

Flexible and easy to cut or install  

Consist of acoustic properties

Contain no organic binder

 

 Application:

Direct exposure to heat as furnace hot face lining

Expansion joint seal

Fire protection
