Abstract
A device () for treatment of exhaust gases includes a housing (); a fragile structure () resiliently mounted within the housing (); and a non-intumescent mounting mat () disposed in a gap between the housing () and the fragile structure (). The mounting mat () comprises melt-formed, leached glass fibers high in silica content and exerts a minimum holding pressure for holding the fragile structure () within the housing () of one of (i) at least 10 kPa after 1000 cycles of testing at a hot face temperature of 900° C., a gap bulk density of between 0.3 and 0.5 g/cm, and a percent gap expansion of 5 percent, and (ii) at least 50 kPa after 1000 cycles of testing at a hot face temperature of 300° C., a gap bulk density of between 0.3 and 0.5 g/cm, and a percent gap expansion of 2 percent.
