Material Notes:
ASPA-2 is a premium grade, lightweight refractory material made from high purity 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 purity, cracking resistance, high strength and resistance to heat are paramount. Due to its exceptional resistance to heat flow for its thickness, it provides maximum thermal resistance where space is at a premium. This material is virtually shot free and is the cleanest refractory paper available. It is ideal for applications up to 1260°C (2300°F). Type ASPA-2 is produced with no organic volatiles and will not produce smoke or odor when heated.Information provided by ZIRCAR Refractory Composites, Inc. (ZRCI)
