Alumina-Silica Fiber PaperZRCI 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 flexiblesheets. 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-97 is ideal for applications up to 1260°C (2300°F).
Uses Include:
- Annealing Cover Seals
- Flexible High Temperature Pipe Insulaiton
- Furnace, Kiln, Reformer and Boiler Lining
- Furnace Door Linings and Seals
- Investment Casting Mold Wrap
- Expansion Joint Seals
- High Temperature Filtration
- Glass Furnace Crown Insulation
- Useful When Refractory Ceramic Fiber Are Not Desired
- Thermal Reactor Insulaiton
- Soaking Pit Seals
- Insulation For Primary Reformer Header
- High Temperature Gasketing

ZRCI 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.
ZRCI Silica-Magnesia Papers Type RSPA-SOL are thermal insulation products capable of withstanding continuous operating temperatures up to 1260°C (2300°F). Type RSPA-SOL papers are designed to have enhanced in-vitro solubility characteristics which enable them to meet European regulatory requirements for synthetic vitreous fibers (European regulatory requirements directive 97/69/ EC). These unique papers exhibit excellent chemical stability and resistance to attack from most corrosive agents. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalis. Type RSPA-SOL papers also provide superior wetting resistance to molten aluminum alloys at high temperatures. Type RSPA-SOL papers will generate small amounts of smoke and trace element outgassing during initial exposure to temperatures above 230º (446ºF).
Uses Include:
- Annealing Cover Seals
- Flexible High Temperature Pipe Insulaiton
- Furnace, Kiln, Reformer and Boiler Lining
- Furnace Door Linings and Seals
- Investment Casting Mold Wrap
- Expansion Joint Seals
- High Temperature Filitration
- Nuclear Insulation Applications
- Glass Furnace Crown Insulation
- Useful When Refractory Ceramic Fiber Are Not Desired
- Thermal Reactor Insulation
- Soaking Pit Seals
- Reusable Insulation For Field Stress Relieving Welds
- Insulation For Primary Reformer Header
- High Temperautre Gasketing
- High Temperature Kiln and Furnace Insulation
- Fire Protection For Pressure and Cryogenic Vessels
- Lining For Incineration Equipment and Stack
