Product Introduction
SUNTHERM High Aluminum Ceramic Fibre Board is manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber board have been further improved due to the higher density.
It is ideal for furnace, boiler duct and stack lining thanks to its low thermal conductivity and low heat storage, which makes the shorter cycle times and quicker access for maintenance in the industrial furnaces possible.
Product Highlight
● Good thermal stability and thermal shock resistance.
● Easy to cut and construct, flexible to operate.
● Resistant to non-ferrous metal penetration.
● Easy to install and use.
● Excellent sound absorption performance.
● Hard and uniform in texture.
