Ceramic fiber felts
Descriptions:
Ceramic fiber felts are produced from corresponding blowing fiber (ST, HA, HP, HZ) with vacuum formed technology.  Ceramic fiber felts 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.
