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.
Excellent Thermal stability :resist devitrification at high Temperature
Low thermal conductivity
Excellent thermal shock resistance
Excellent chemical stability
Good sound absorption
Low heat storage capacity
STD : 1260 ° C
