GENERAL INFORMATION
ZIRCAR Refractory Composites, Inc.
offers a wide range
of insulating refractory papers. These non woven, non-asbestos, fiber-based
products are engineered as thermal barrier materials for use in high
temperature applications up to 1450°C (2642°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's line of refractory paper include a binderless product for
applications where outgassing cannot be tolerated, non-respirable grades where
fiber content is of concern, and high purity compositions where the reducing
of silica cannot be permitted.
An additional type of refractory papers consists of soluble, Non RCF
fibers formed into highly insulating sheets. The fibers are soluble in body
fluids and offer an alternative to refractory ceramic fiber blankets. These
grades of materials meet European regulatory requirements, (Directive
97/69/EC). Please refer to Refractory Sheet Type RSPA-SOL

Alumina-Silica Fiber Paper
ZIRCAR Alumina-Silica Fiber Paper Type ASPA-1 and ASPA-2
are premium grade, lightweight refractory material made from high purity
alumina-silica fibers formed into a highly flexible sheets. These
alumina-silica fiber papers exhibit very low thermal conductivity and are
designed for use in applications where purity, cracking resistance, high
strength and resistance to heat are paramount. Due to their exceptional
resistance to heat flow for their thickness, they provide maximum thermal
resistance where space is at a premium. These materials are virtually shot
free and are the cleanest refractory papers available. They are ideal for
applications up to 1260°C (2300°F).
Type ASPA-1 contains an organic binder to provide increased handling
strength at room temperature. It possesses excellent chemical stability and
resists attack from most corrosive agents. Because of its high purity
chemistry, it resists oxidation and reduction. If it becomes wet due to water,
steam or oil, its physical and thermal properties will return upon drying.
Type ASPA-2 is produced with no organic volatiles and will not produce smoke
or odor when heated.
ZIRCAR Alumina-Silica Fiber Paper Type ASPA-970
is an industrial grade, lightweight refractory material made from
alumina-silica fibers formed into highly flexible sheets. This alumina-silica
fiber paper exhibits very low thermal conductivity and is designed for use in
applications where flexibility, high strength and resistance to heat are of
paramount. Type ASPA-970 is ideal for applications up to 1260°C (2300°F).
Type ASPA-970 is available in a variety of thickness.
ZIRCAR Alumina-Silica Fiber Paper Type
ASPA-880 is a high temperature, lightweight refractory material made from
alumina-silica fibers formed into highly flexible sheets. It is made from
shorter and smaller diameter fibers with a higher alumina content and are laid
up at significantly higher density. These factors lead to high temperature,
slow shrinkage, higher strength, and better chemical resistivity. This
alumina-silica fiber paper exhibit very low thermal conductivity and is
designed for use in applications where flexibility, high strength and
resistance to heat are paramount. Type ASPA-880 exhibits low thermal
conductivity and is ideal for applications up to 1450°C (2642°F). It
is used in environments where standard ceramic fiber papers will not survive.
