Patent ID: 8182752

Claim:
A mounting mat comprising: heat treated inorganic fibers; and a holding pressure performance increasing surface treatment comprising an inorganic particulate on at least a portion of the exterior surfaces of at least a portion of the inorganic fibers, wherein said mounting mat has a minimum holding pressure for holding a fragile structure within a housing of at least one of (i) 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 3 , and a percent gap expansion of 2 percent, and (ii) 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 3 , and a percent gap expansion of 5 percent.
