Feature

Application:

Ceramic Fiber Board is made of Alumino-Silicate fibrous wool by vacuum forming process.

Furnace with high temperature and high gas flow velocity

Characteristic:

Fibers are bonded by binder

Low density and low thermal conductivity

Shorter heat up and cool down time

Resilience and resistance to thermal shock

Greater mechanical strength

Can withstand gas flow velocity of 30 m/sec

Even density, thickness

Flexible and easy to cut or install

Asbestos free
