All kinds of ceramic fiber boards, adopting corresponding blowing fiber(ST) as the material, are produced by vacuum formed technology.
All kinds of ceramic fiber boards, do not only possess the same function of fiber, but also have hard texture, excellent toughness and intensity, and excellent fire resistant and heat preservation.
2. Characteristics:
Low thermal conductivity and low heat storage
Excellent thermal stability and thermal shock resistance.
Excellent toughness
3. Usage:
Liners of industrial furnace
High temperature liner, vehicle, baffle of furnace door, disjunctive board of temperature
High temperature equipment insulation, heat preservation.
Space navigation, ship building, heat insulation fireproofing, sound insulation, insulation
