ABSTRACT:
The invention provides an intumescent sheet material comprising 25 to 60 dry weight percent of at least one unexpanded intumescent material, 25 to 60 dry weight percent of ceramic fibers, 0.5 to 5 dry weight percent of glass fibers having a diameter of less than about 2 microns, and 0.1 to 15 dry weight percent of organic binder, wherein said intumescent sheet material has a cold erosion rate of less than 0.05 grams/hour. The invention also provides catalytic converters and diesel particulate filters containing the sheet material.
