| 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.
