Made from bulk fibres produced by the most modern spinning process, giving exceptional length and uniform distribution which are ideal for manufacturing blanket of controlled density, high tensile strength and resiliency. They have superior acoustic as well as thermal insulation characteristics. It is ideal for furnace, boiler duct and stack lining due to its low-thermal conductivity and low-heat storage allowing shorter cycle times and quicker access for maintenance.

Features 
Low thermal conductivity
Excellent thermal shock resistance

Low heat storage capacity
Lnorganic - smoke free

Applications:
Mainly serve as the ceramic fiber lining for industrial furnaces, heating equipment and high- temperature pipelines, such as
Metallurgy Industry: heating furnaces, heat treatment furnaces and ladle insulated cover
Mechanism industry: thermal insulation material for electric power boilers, gas turbine engine and nuclear power plant
Petrochemical industry: the lining of high-temperature reaction equipment and heating equipment in chemical fields, like converting furnaces, constant/reduced pressure furnaces, cracking furnaces, flue lining.
Ceramics and electro ceramics: roller hearth furnaces, tunnel furnaces , shuttle furnaces and other kinds of furnaces
