XPE®‑AV2 and XPE® AV2i Support Mat

XPE®-AV2 and XPE®-AV2i Support Mats are advanced intumescent expanding mat products 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 features of AV2 with the following additional benefits:

  • Lower organic content resulting in improved mat performance and converter robustness.
  • Improved handling properties which will reduce part defects during canning operations.
  • Eliminates the need for tape backing.

Unifrax emission control products and solutions are made to meet the demands of stringent regulations and difficult operating conditions. We offer a variety of mounting mats and insulation materials in three proven fiber chemistries: Polycrystalline Wool (PCW), Refractory Ceramic Fiber (RCF) and Alkaline Earth Silicate (AES). Our strong focus on product development, manufacturing efficiencies and sophisticated quality control programs positions Unifrax to be your preferred resource for innovative solutions for emission control applications in worldwide markets.
