Product Description

Description:
It is a micro-porous insulation material with very good insulating properties. It has an extremely low coefficient of thermal conductivity. Compare thermal insulation performance with the traditional fiber insulation material is 3 ~ 4 times better, which is the best performance thermal insulation material so far.
It consists of inorganic silicates. The main constituent is fumed silica, the other components are opacifiers for minimizing infrared radiation and reinforcing glass fibers. It is heat sealed in a close-fitting 15 μm PA/PE laminated film for the purposes of flexibility. It can be used up to a maximum application temperature of 1000ºC.


Feature:
• Ultra-thin insulation: 15mm thickness, high efficiency insulation
• Lower temperature: shell temperature drop 50 ~ 70ºC
• High efficiency and energy saving: reduce heat dissipation by 40~60%
• High strength compression: refractory brick groove shallow 15mm, high brick Angle strength
• Life guarantee: the overall strength of firebrick is good, and the service life of transition zone is long (over 18 months)



Application: 
Transition zone of cement rotary kiln.
