Heavy Duty/Commercial, On and Off Road Vehicles

Heavy duty vehicles pose challenging design requirements for after-treatment devices.  Unifrax offers a range of support mat products to meet a variety of temperature, gap and loading requirements.


Ecoflex 400 support mats are available as a single layer solution in a wide range of basis weights for quick and easy installation in various gap applications.  The highly resilient Saffil and M-Fil fibers offer an ideal solution to high gap expansions commonly experienced in heavy duty diesel after-treatment devices.


CC-Max 5 support mats offer a cost effective alternative to the Ecoflex family of support mats.  This product’s unique refractory ceramic fiber formulation provides a support mat with a holding force sufficient for keeping heavy DPF, SCR and DOC intact as the vehicle experiences high vibration and regeneration cycles.


XPE-MP® provides the best value, most cost effective solution designed for heavy duty diesel applications with proven performance on EPA-2007, EPA-2010 and off road systems.

 Isomat® “Green” Support Mats

The Isomat® family of support mats offers the option of using low bio-persistence fibers without compromising product performance.  Isomat support mats are manufactured using patented, highly resilient alkaline earth silicate (AES) fibers and are available with and without vermiculite to meet application needs.


Our premium performance AES fiber mat, Isomat® AV5, has been used in approximately 20 million devices in light duty and heavy duty vehicles meeting Euro IV, Euro V, and Euro VI regulations.


Isomax® 1, our fiber-only support mat made with AES fibers is ideally suited for both light and heavy duty applications where use of low bio-persistence fibers is required.
