Product Data

Brightcross Standard RCF shapes are produced by dewatering a  slurry containing  ceramic fibre, starch and silica. The  resulting items  when dried are rigid, pure white, low density and exhibit the following properties:

  • High temperature stability
  • Low thermal conductivity
  • Low heat storage
  • Low density
  • Good thermal shock resistance
  • Good corrosion resistance
