Product Data
Brightcross vacuum formed inhibited RCF shapes are produced by dewatering a slurry containing ceramic fibre, inhibitor (inert fluoropolymer) starch and silica.
The resulting items when dried are rigid, low density and exhibit the following properties:
- Coloured pale blue-green to identify as inhibited.
- High temperature stability.
- Low thermal conductivity.
- Low heat storage.
- Low density.
- Good thermal shock resistance.
- Good corrosion resistance.
