2103706 9218435 PCTABS00016 The invention pertains to materials which resist combustion and expand when subjected to high temperatures, and are thus suitable for use as mounting mats for monoliths in catalytic converters. Previously known intumescent materials, such as vermiculite, exhibit contraction between about 100 ·C and 400 ·C, which may cause a monolith to become loose from the casing during warm-up of the catalytic converter. A monolith can be mounted in a catalytic converter by a material containing intumescent vermiculite flakes that have a uniform content of chemically bound water, from 1.0 to 3.2 % by weight and a uniform bulk density, from 0.2 to 0.9 g/cm3. Such a mounting affords good support to the monolith at warm-up temperatures, exerts adequate holding forces at operating temperatures without danger of cracking the monolith, and does not incur gradual reduction in holding forces at operating temperatures.
