Ceramic fiber boards
|
|
Descriptions:
|
|
Ceramic
fiber boards are produced from corresponding blowing fiber (ST, HA, HP, HZ)
with vacuum formed technology. Ceramic fiber boards not only possess the typical function of ceramic fiber, but also 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.
