Alumina-Silica Paper Type ASPA-1 & ASPA-20 pages

REFRACTORY PAPERS
ZIRCAR Refractory Composites, Inc. produces a wide range of insulating refractory papers. These non woven, nonasbestos, 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, nonrespirable grades where fiber content is of concern, and high purity compositions where the reducing of silica cannot be
permitted. One of these 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).
Alumina-Silica Fiber Paper
ZRCI 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.
ZRCI 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.
