Overview
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
