摘要： The disclosure relates to flexible heat expanding, fire retardant composite materials comprising an intumescent component in granular form, an organic binder component such as an elastomer, an organic char-forming component and fillers such as clay, silica, synthetic organic staple fibers or inorganic fiberglass or ceramic fibers. These composites, when subjected to heat at about 110.degree. C., can intumesce up to ten times their original volume.

摘要： An intumescent composite comprising a layer of intumescent sheet material having a restraining layer laminated thereto provides a superior intumescent barrier for use in sealing penetrations through floors, partitions and ceilings from smoke, fire, gas and water passage. The restraining layer causes the intumescent reaction to be generated in a directionalized manner and can be utilized to assure that the penetration cavity is optimally filled. The intumescent composite can have holes punched in it and can be used in fire protection applications where air circulation is desired. In the event of a fire, the expansion of the intumescent composite is in a direction which enable the punched holes to be quickly filled.

摘要： Penetrations or passageways through fire resistant walls, floors, partitions and ceilings are frequently necessary to provide for present or future pipes, cables or conduits. A device fixed to the walls of the penetration provides a barrier to prevent the passing of fire, heat, smoke and toxic gases, and water through the penetration under adverse conditions of fire or elevated temperatures. The device includes at least one end cap capable of providing a cold smoke seal. An intumescent material which in the event of excessive heat or fire, foams and expands to substantially fill the penetration, is provided. The device may include a laminated restraining layer to provide assurance that the char formed during the intumescent reaction to fire and heat, is generated so that the penetration cavity is optimally filled.
