SUPERCERA Blanket
is a refractory fibre needled mat made without binder from Supercera fibres-the
only super-spun double needled fibre in the country today. Supercera RTZ and HTZ
Blankets are zlrconla stablilsed and are suitable for use upto 1260°C and 1425°C
respectively. Both blankets have excellent resistance to most chemicals. If wet
by oil or water, their thermal and physical properties are fully restored upon
drying.

OUT-STANDING
ADVANTAGES |
APPLICATIONS |
- Excellent Thermal Stability
- Low Shrinkage at elevated temperature
-due to their excellent Thermal Stability
- Low Heat Storage Both blankets
store approximately 95% less heat than dense firebrick and approximately 75% less
heat than insulating firebrick- a property of significant importance in the operation
of periodic kilns/furnaces
- Good Cold Strength
- Excellent Hot
Strength
- Thermal Shock Resistance Due to the flexible matrix ofSupercera,
extreme temperature changes do not alter its ability to physically stay in place
and perform at highest levels.
- The products are not welted by molten non-ferrous
metals. If wet by oil, water or steam, thermal and physical properties will be
fully restored after burn out or drying.
