Apparatus are provided for a device with improved heat resistance. The device includes a body and an encasing layer disposed substantially entirely around the body. The encasing layer includes a fabric layer and a coating. The fabric layer has a first end and a second end coupled together about the perimeter of the body to enclose the body, and the fabric layer includes an exterior surface. The coating is disposed on the exterior surface of the fabric layer, and the coating forms a barrier for the fabric layer.

A ventilation duct for a fire rated ventilation duct wall penetration has one or more metal sheets forming said duct, wherein said metal sheet duct is covered on the outside by a heat insulating material, and said duct includes elongated stiffening members located on the outside of the duct and attached to said metal sheets. The stiffening members each comprises a metal profile and at least one non-combustible bar of inorganic material. The metal profile is fixed to the metal sheet of the duct and retains the non-combustible bar by at least partly encircling the bar.

A flexible conduit or sleeve sized for surrounding and supporting a movable wire rope includes an inner core having an opening for receiving the movable wire rope, a plurality of wires disposed about the inner core, and an outer sleeve. The outer sleeve is made from a polymer material having a flame retardant additive that provides sufficient flexibility while also improving manufacturability for use in various applications, such as part of an aircraft seat adjustment mechanism.

In order to provide passive fire protection for a member, casing portions that are physically discrete from each other and from the member are made by injection molding of fluid fire-resistant material (which may be intumescent), and allowing the material to cure. The inner surfaces of the casing portions are complementary in shape to a portion of the outer surface of the member. The casing portions collectively form a casing that surrounds the outer surface of the member, with their inner surfaces abutting against the outer surface of the member. The casing portions are secured to the member by a removable strap or collar, an adhesive, or both.

A thermal protection device includes a cover including a wall, according to a longitudinal axis, with a rear portion adapted to be mounted on the connector so as to surround it at least partially and with a front portion adapted to be mounted on the tubular element and to hold it by a mechanical connection.

Heat resistant systems provide a self-activating insulative solution. A seal system includes a case defining a joining line where two sections of the case join together. The case envelops an internal space and separates the internal space from an external space. A seal is disposed at the joining line and a case extension defines a cavity on an outside of the seal. The case extension has an opening that extends between the cavity and the external space. A lining of a heat responsive material is provided in the case extension. The material expands to an activated state when exposed to heat above a threshold temperature and passes through the opening encapsulating the case extension and insulating the seal from the external space.

The present invention provides a sheet-like thermal insulating material (flame barrier insulating laminate) that is shapable into a three-dimensional and has excellent handling properties, and a thermal insulating structure with a three-dimensional shape made from the laminate. The flame barrier insulating laminate comprises at least one flame barrier insulating layer and one prepreg layer. The flame barrier insulating layer is made of a sheet having a thickness of 0.1 to 3.0 mm, in which inorganic fibers with a heat resistance temperature of 1000 C. or higher are entangled in a random direction. The prepreg layer is a prepreg sheet in which an inorganic fiber base fabric is impregnated with a semi-cured thermosetting resin. The thermosetting resin of the prepreg layer in the flame barrier insulating laminate is fully cured, resulting in a flame barrier insulating structure with a desired shape.
