Abstract
A flexible, resilient, intumescent mat material comprising fiber, binder, and an intumescent agent which includes a mixture of unexpanded vermiculite and expandable graphite undergoes intumescence at a lower temperature, with an enhanced degree of expansion and with a lesser degree of contraction upon prolonged heating. The intumescent mat can be employed in catalytic converters for motor vehicles and as a firestop material.
