Abstract: A flexible fibrous material comprises inorganic fibers and a binder and methods of making the same. The binder comprises at least one of: a first organic polymer having anionic groups and a flocculent, the flocculent comprising a second organic polymer having cationic groups; or a reaction product of the first organic polymer and the flocculent. Flexible fibrous material according to the present invention may be used as components in certain pollution control devices.

Abstract: A three dimensional flame barrier is described herein. The three dimensional flame barrier comprises a flame resistant material, wherein the flame resistant barrier has a complex geometry that is defined by a height, width and length, wherein the height of the complex geometry is substantially greater than the thickness of the flame resistant material from which it is formed wherein the flame resistant material comprises inorganic fibers, inorganic particles and an inorganic binder. In some embodiments, the flame barrier article can further comprise a fire protection coating disposed on a first major surface of the flame barrier material.
