Introduction:
Ceramic fiber boards are high performance insulation products manufactured from ceramic fiber bulk and binders, with unique shot removing and vacuum forming process, they offer low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock and chemical attack.

Features:
1.Low thermal storage, low thermal conductivity.
2.Excellent chemical stability.
3.Excellent thermal stability and thermal shock.

Application:
It can be used for industrial furnace lining,heating equipment wall lining and back lining,ceramics kilns thermal insulation ,molten metal thermal insulation, etc.
