Governmental regulations have dictated that automobile manufacturers produce lower emission products. With the addition of a Diesel Particulate Filter (DPF) this can be accomplished and remove 85-100% of NOx emissions. This is not only better for the environment, but better for your health by reducing smog and creating cleaner air.

DPFs operate in extreme conditions with high vibration and elevated temperatures. TREO™ is the ideal insulation for the typical operating conditions of diesel particulate filters. By removing large shot in our patented process results in and insulation with excellent vibration resistance and superior thermal performance.
