REFRACTORY SHEET
TYPE RS-CLOTH & RS-TAPE
GENERAL INFORMATION
ZRCI Refractory Sheet Types RS-Cloth and RS-Tape are fiber
reinforced alumina composites in a highly flexible form. They
are received dried, when wetted 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 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.
