Material Notes:
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).Information provided by ZIRCAR Refractory Composites, Inc. (ZRCI)
