- Breif Description: 1430 WOOL 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: Contain Zirconia Non-combustible
Can withstand temperature up to 2600o F Asbestos free
Low density and low thermal conductivity Contain no organic binder
Light weight with low thermal mass Consist of acoustic properties
Shorter heat up and cool down time Flexible and easy to cut or install
Resilience and resistance to thermal shock Needled blanket
Application: Direct exposure to heat as furnace hot face lining Fire protection
Expansion joint seal
Classification temperature 1430oC (2600o F)
Melting point 1700oC (3100o F)
Fiber diameter 2.8 micro meter
