REFRACTORY SHEET TYPES RS- CLOTH &
RS-TAPE
ZRCI Refractory Sheet Types RS-Cloth and
RS-Tape are fiber reinforced alumina
composites in a highly flexible form. They are received dried, when wet with
water or AL-HARD Hardener they become extremely
flexible. They can be wrapped into many simple or complex shapes and will stick
to themselves. When dried they become an extremely hard, strong, self supporting
composite structures. RS-Putty can be used to burnish any surface and provide a
very smooth hard finish. After a low temperature bake-out of 300°C (570°F)
RS-Cloth and RS-Tape are unaffected by moisture.
They offer the strength, durability, flexibility and
versatility required by many high temperature applications up to 1300°C (2373°F).
Their high alumina content makes Refractory Sheet RS-Cloth and RS-Tape highly
resistant to many environments including Hot Glass handling, molten aluminum and
chemical and petroleum processing. After they are baked out they are not
affected by water as well as many types of fuel oils.
When hardened with
AL-HARD Refractory Sheet RS-Cloth and RS-Tape
become "rock hard" for greater strength

variables such as the stresses, both thermal and mechanical, and the environment
that the insulation experiences.
