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 our catalytic converter support mats. Engineered to meet the performance requirements associated with traditional catalytic converter applications, Unifrax is pleased to offer XPE®-NV substrate support mat.Unifrax XPE-NV provides a unique balance of performance versus value and is recommended for a broad range of catalytic converter substrate support and cone insulation applications. XPE-NV can be engineered to provide excellent thermal stability at inlet gas temperatures up to 950°C. The support mat will expand with increasing relative thickness when first exposed to temperatures in excess of 325°C. Expansion pressure is provided by vermiculite particles trapped in a structural support matrix of Fiberfrax® ceramic fibers. The ceramic fibers also provide resistance to hot gas mat erosion.Information Provided by Unifrax I LLC
