Publication number: 20070125018Abstract: A firestopping apparatus for providing a fire barrier in a construction barrier. The apparatus is comprised of a sleeve within which there are located intumescent pads that are oriented to form a confinement area therebetween to accommodate various penetrating members such as cables, conduits and the like that need to pass through the barrier. Upon sensing the heat from a fire, the intumescent pads seal around the penetrating members to prevent the fire from passing through the barrier. One or both of the intumescent pads is movable toward or away from the other so that the confinement area can be adjusted in size, that is, the confinement area can be increased in size to accommodate a large number of penetrating members of decreased to accommodate a lesser number. One or both of the intumescent pads may be biased in the direction toward decreasing the size of the confinement area.Type: ApplicationFiled: November 18, 2005Publication date: June 7, 2007Inventor: James Stahl

Patent number: 5137658Abstract: An intumescent material and a process for forming of an intumescent material is disclosed including a two stage intumescent expansion characteristic. The composition includes an intumescent material having a primary expansion ingredient such as expanding graphite in combination with a pre-expansion material adapted to provide intumescent expansion at a temperature less than that of the primary expansion material. The pre-expansion material preferably is a liquid isobutane encapsulated within microspheres of any latex material or polyvinylidene. The pre-expansion step allows for a low density mass having fairly uniform dimensions relative to the original proportions of the specimen. A novel process for forming same allows heating to a temperature greater than the pre-expansion temperature within a closed mold to prevent pre-expansion by containment therein and still allow heat fusing of the fire barrier form.Type: GrantFiled: January 27, 1992Date of Patent: August 11, 1992Assignee: Specified Technologies Inc.Inventor: James Stahl
