  • Patent number: 8071040
    Abstract: A mounting mat for an exhaust gas treatment device including high temperature resistant ceramic fibers containing alumina and/or high temperature resistant biosoluble inorganic fibers, organic binder which at least partially liquefies at elevated temperature prior to binder burnout, colloidal inorganic oxide and optionally intumescent material. The exhaust gas treatment device includes a housing, a fragile catalyst support structure resiliently mounted within the housing, and the mounting mat disposed in a gap between the housing and the fragile catalyst support structure.

  • Patent number: 5989736
    Abstract: A paper composite includes activated carbon fibers and inorganic fibers bound together by an organic latex binder. Such a ceramic paper is useful in a variety of applications and is particularly useful as a filter media in the filter unit of an inflator in an automotive airbag. The filter media is particularly suitable for use with non-azide generants within an airbag inflator.

  • Patent number: 5834120
    Abstract: A fire protection material is provided for protecting electrical cables and components. The material comprises an endothermic-reactive insulating fibrous material including an inorganic endothermic filler which undergoes multiple endothermic reactions between the range 100.degree. C. and 750.degree. C.; inorganic fiber material; and an organic polymer binder. The weight ratio of endothermic filler to inorganic fiber is preferably in the range of 0.25 to 3.0. The fire protection material is in the form of semi-rigid or rigid board or may be moulded into sections.
