Unifrax XPE® AV2/AV2i Substrate Support Mat

XPE®-AV2 is an advanced intumescent expanding mat designed to function as mechanical support for the ceramic substrate and act as an exhaust gas seal while providing thermal insulation. When compared to traditional expanding mats, XPE-AV2 offers improved holding force at low temperatures as well as superior erosion resistance. XPE®-AV2i offers the same performance with the following benefits:Lower organic content resulting in improved mat performance and converter robustnessImproved handling properties which will reduce part defects during canning operationsEliminates the need for tape backingXPE-AV2/AV2i advanced expanding mat offers excellent thermal stability with a continuous use temperature of 800°C average mat temperature. The mat expands with increasing relative thickness when first exposed to temperatures in excess of 325°C.Information Provided by Unifrax I LLC
