Material Notes:
Developed to meet the most stringent European regulatory requirements, IsoMat AV/Avi is engineered utilizing the unique Isofrax® 1260°C fibers - a revolutionary green fiber produced using patented magnesia-silicate chemistry.These fibers are the product of a long-term research and development effort by Unifrax to produce a biosoluble fiber with high-temperature performance characteristics up to 1260°C. Isofrax fibers exhibit excellent chemical stability and resistance to attack from most corrosive agents including combustion by-products of gasoline and diesel fuels.Mat Performance and Applications: As a manufacturer of fibers used in a variety of catalytic converter mounting systems, Unifrax has successfully combined fiber-making expertise with a state-of-the-art paper manufacturing process to maximize the performance of IsoMat AV/AVi. Like intumescent support mats utilizing traditional ceramic fibers, IsoMat AV/AVi can be designed to provide excellent holding force at continuous operating temperatures up to 900°C inlet gas temperature. Additional holding force is provided by vermiculite particles trapped in a structural support matrix of Isofrax fibers. The fiber matrix provides resistance to hot gas mat erosion. IsoMat AV/AVi expands with increasing relative thickness when first exposed to temperatures in excess of 325°C.Information Provided by Unifrax I LLC
