    摘要: A device (10) for treatment of exhaust gases includes a housing (12); a fragile structure (18) resiliently mounted within the housing (12); and a non-intumescent mounting mat (20) disposed in a gap between the housing (12) and the fragile structure (18). The mounting mat (20) comprises melt-formed, leached glass fibers high in silica content and exerts a minimum holding pressure for holding the fragile structure (18) within the housing (12) 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/cm3, 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/cm3, and a percent gap expansion of 2 percent.
