Ceramic fiber board

Product description:

By adding a small amount of high-purity alumina silicate fiber binders, RACOFIBER™ ceramic fiber board is made through automation control and continuous production process, with a host of features such as precise size, good flatness, high strength, lightweight, excellent thermal shock resistance and anti-stripping.

Features:

Low heat capacity, low heat conductivity
Compression strength
Weathering resistance and long service life
Good flame and airflow shock resistance performance
Good thermal stability
Easy cutting and installing

Application

RACOFIBER™ ceramic fiber board has good performance in resistance to mechanical damage, the typical application scope:
pushed slab kiln, ladle furnace, bell kiln, tunnel kiln, roller kiln, Aluminum Melting Furnace, backing and wall lining of the heat treatment furnace .
high temperature shield board
commonly used heat resistance material
insulation of duct, kiln car
all kinds of high temperature industrial insulation
