Ceramic Fiber Paper with Aluminum Foil

CeraTex^® 3170AF

CeraTex® Ceramic Fiber Paper with Aluminum Foil is an alumino-silicate ceramic fiber-based non-woven fabric with a single-sided layer of laminated aluminum foil. It is manufactured through a special paper-making process with high purity washed fibers, suitable for high temperature insulation up to 2300°F.

Cross-reference: CeraTex 3170 is an equivalent/superior equivalent of the following styles: Unifrax Fiberfrax® 550, 970; Thermal Ceramic Kaowool 900; Lydall/Lytherm 1530, 1535.
