Abstract:
A non-intumescent mat for providing support for a fragile structure in a low temperature exhaust gas treatment device comprising up to about 1260.degree. C. temperature resistant, amorphous, inorganic fibers, said fibers having a Young's Modulus of less than about 20.times.10.sup.6 psi and a geometric mean diameter less than about 5 .mu.m, said mat optionally including a binder, wherein the mat is adapted to provide a holding force of at least 15 psi throughout an average mat temperature range from ambient temperature up to at least about 350.degree. C., wherein the temperature resistant, amorphous, inorganic fibers are melt formed and are not post processed by heat treating to either anneal or crystallize the fiber.
