GENERAL INFORMATION
ZIRCAR Refractory Composites, Inc. insulating blankets
are non woven, inorganic, fiber-based products that contain no asbestos.
They are engineered for use as thermal barrier materials in high
temperature applications up to 1260°C (2300°F). Commonly used in the molten metal casting and heat treating industries,
ZRCI materials are also used as specialty gasketing in the fuel cell,
nuclear, glass and electronic industries, as well as many other
applications which require high temperature stability and low thermal
conductivity. They also offer excellent corrosion resistance and unique
handling strength for easy die-cutting, wrapping and forming.

ZRCI Silica-Magnesia Blanket Type RSBL-SOL
is
made from soluble NON RCF fiber formed into a mechanically needled
flexible blanket capable of withstanding continuous operating temperatures
up to 1260°C (2300°F). It is designed to have enhanced in-vitro
solubility characteristics. The fibers are soluble in body fluids and
offer users an alternative to refractory ceramic fiber blankets. Type RSBL-SOL
Blankets meet European regulatory requirements (Directive 97/69/EC).
Type RSBL-SOL is an inorganic, needled insulating
blanket which is manufactured using 1260°C (2300°F) spun fibers. These
extra long spun fibers, cross-locked through a unique forming process,
produce a blanket with good handling strength. It has excellent chemical
stability and is unaffected by most chemicals except hydrofluoric and
phosphoric acids and concentrated alkalis. If wet by water or steam,
thermal and physical properties remain unaffected after drying. Type RSBL-SOL
Blankets also provide superior resistance to attack from molten aluminum
alloys at high temperatures.

|
Type RSBL-SOL Blankets provide solutions to
a variety of heat processing problems. They are available in a variety of thickness
and densities. They are ideal for use as furnace insulation in sintering,
heat treating and chemical thermal process systems. They can be layered
between rigid insulation, wrapped around process piping or fabricated into
folded modules. They are also useful as insulation packing in furnace
spaces, around furnace sight tubes & ports and fill in expansion
joints and masonry cracks.
