DESCRIPTION
STD/Cera: Refractory fibre made from alumina and silica.
AZS/Cerachem: Refractory fibre made from Alumina, Silica and Zironia. All above fibres are resistant to chemical attack, except for hydrofluoric and phosphoric acids and strong alkalies.
FEATURES
- Low thermal conductivity
- Excellent thermal shock resistance
- Excellent chemical stability
- High resiliency
- Good sound absorption
- Low heat storage capacity
- Excellent Thermal stability :resist devitrification at high Temperature
