Unifrax Fiberfrax® 880 Ceramic Fiber Paper
Categories:	Ceramic; Oxide; Aluminum Oxide; Silicon Oxide
Material Notes:	880 paper is made from a higher alumina content, shorter, smaller diameter fiber and laid up at higher densities. These product parameters lead to reduced shrinkage, higher strength, an increased operating temperature range and better chemical resistivity. This product is used in appications where the service life of standard ceramic fiber papers is reduced. Information Provided by Unifrax I LLC
