A fire barrier laminate including: at least one non-fibrous fire barrier layer directly or indirectly coated onto at least one first polymeric flame propagation resistant film layer; at least one second film layer proximate to the non-fibrous fire barrier layer opposite the first polymeric flame propagation resistant film layer; at least one scrim layer disposed: (i) between the non-fibrous fire barrier layer and the first polymeric flame propagation resistant film layer; and/or (ii) between the non-fibrous fire barrier layer and the second film layer; and/or (iii) proximate to the first polymeric flame propagation resistant film layer opposite the non-fibrous fire barrier layer; and/or (iv) proximate to the second film layer opposite the non-fibrous fire barrier layer. Also, a method of making the fire barrier laminate.

A multilayer thermal insulation composite for fire protection applications. The composite includes a fibrous insulation layer, at least one inorganic heat absorbing layer disposed on one side of the fibrous insulation layer, and at least one superinsulation layer disposed on at least one side of the composite adjacent the heat absorbing layer or the fibrous insulation layer. The composite may further include a scrim layer comprising a high temperature resistant, flexible, woven or non-woven scrim or scrim and high temperature resistant material disposed around the multilayer thermal insulation composite partially or substantially totally encapsulating the composite. The composite is lightweight and flexible, exhibits reduced heat transfer to the cold-face, with improved thermal insulation capability.

A porous ceramic (honeycomb) structure skin coating and a method of producing a porous ceramic structure skin coating which provides a hardshell, strong, acid- and alkali-resistant, chip-resistant ceramic honeycomb structure coating which resists pollution control catalyst from being absorbed into the skin coating.

A flexible or rigid intumescent material for fire protection applications. The intumescent material includes inorganic fibers, intumescent material, and a char strength enhancer that is different from the intumescent material and binder. The intumescent material exhibits a high expansion ratio and char strength, without substantial shrinkage, in response to elevated temperatures normally encountered during a fire.

Intumescent material for fire protection

An insulated double-walled pipe including an inner pipe, an outer pipe surrounding the inner pipe to provide a substantially uniform annular gap between the inner and outer pipes, and optionally an annular flange connected to at least one end of the inner and outer pipe, wherein the annular gap is substantially filled with an insulating paste comprising a fiber component, an inorganic binder component, and optionally a vermiculite component, a filler component, and an organic binder component. A method for preparing the insulated double-walled pipe includes providing a double-walled pipe having an annular space between the walls; introducing an insulating paste material into the annular space; freezing the insulating paste material in the pipe; bending the pipe; and thawing and gelling the paste material.

Provided is a lightweight, fibrous thermal insulation panel including high temperature resistant biosoluble inorganic fibers, expanded perlite, binder, and optionally conventional high temperature resistant inorganic fibers. Further provided is a method for preparing a lightweight, fibrous high temperature thermal insulation panel including: (a) providing an aqueous slurry comprising from about 15% to about 90% high temperature resistant biosoluble inorganic fibers, from about 10% to about 80% expanded perlite, at least one of from 0% to about 50% organic binder or from 0% to about 20% inorganic binder by weight, and optionally from 0% to about 70% conventional high temperature resistant fibers; (b) forming the lightweight, fibrous thermal insulation panel by depositing the said aqueous slurry onto a substrate; (c) partially dewatering the slurry on the substrate to form a fibrous layer; and (d) drying the fibrous layer to a moisture content of no greater than about 5% by weight.

A support element is disposed between a housing and a fragile structure resiliently mounted within the housing. The support element includes an integral, substantially non-expanding ply or layer of melt-formed ceramic fibers containing at least alumina and silica. The fibers have an average diameter ranging from about 1 micron to about 14 microns and have been prepared by a process of heat treating under a time-temperature regimen of one of (i) heat treating said fibers at a temperature of 990&#xb0; C. to at least 1050&#xb0; C. for greater than 1 hour such that the treated fibers have about 5 to about 50 percent crystallinity as detected by x-ray diffraction, and a crystallite size of about 50 &#x212b; to about 500 &#x212b;, or (ii) heat treating said fibers at a temperature of greater than 1050&#xb0; C. for an effective time such that the treated fibers have about 5 to about 50 percent crystallinity as detected by x-ray diffraction, and a crystallite size of about 50 &#x212b; to about 500 &#x212b;. The resultant support element provides a minimum residual pressure for holding the fragile structure within the housing of one of at least 4 psi after at least 200 cycles of testing at 900&#xb0; C. or at least 10 psi after at least 1000 cycles of testing at 750&#xb0; C. Such a support element may be used in devices for the treatment of exhaust gases such as catalytic converters, diesel particulate traps and the like. A method of mounting a fragile structure in such a device is also provided.
