Ceramic Fiber Boards
Ceramic fiber boards are produced from refractory
ceramic fiber with inorganic binders using vacuum
formed technology.   In addition to possession of the
typical function of ceramic fiber, the boards have hard
texture, excellent toughness and intensity, and excellent
fire resistance and heat preservation. They feature low
thermal conductivity and low heat storage, excellent
thermal stability and thermal shock resistance, and
outstanding acoustic insulation.

Ceramic fiber boards are uniform in bulk density and
thickness, therefore provides excellent consistency in
product geometry.
