Patent number: 6793993Abstract: A fire resistant resilient insulation assembly, includes: a resilient insulation and a fire resistant polymeric film forming a tubular envelope surrounding the resilient insulation. The fire resistant polymeric film includes: 50 to 80 weight percent high density polymeric material; 5 to 45 weight percent linear low density polymeric material; 5 to 25 weight percent fire retardant concentrate (a halogen and a synergist in a polymeric carrier); 0 to 5 weight percent UV stabilizer; and 0 to 10 weight percent pigment. Preferably, the film is a two layer coextruded film with the outer layer being a predominately linear low density polymer that provides a good finish for printing and a relatively high coefficient of friction to improve the handling of the film during the encapsulation of the blanket. The inner layer is predominately high density polymer that provides the coextruded film with the impact strength and tear resistance required for processing and handling.Type: GrantFiled: August 19, 2002Date of Patent: September 21, 2004Assignee: Johns Manville International, Inc.Inventors: Richard J. Ray, Blake Boyd Bogrett, Majid Hindi, Loye Dwayne Fant

Patent number: 6787214Abstract: Fire-retardant sheet element can be composed of several fire protection glass plates (2, 3). Lateral edges (9, 10) of adjacent glass plates (2, 3) therein abut one another. Into the interspace (26) between lateral edges (9, 10) a sealing configuration (7) is installed. This comprises an addition element (22) and elastic sealing elements (23, 24). The glass plates (2, 3) comprise several glass panes (16) and interspaced fire protection layers (18). These fire protection layers (18) do not extend up to the edges (9, 10) and are sealed in the regions of the lateral edges with a barrier material (20). No additional frame elements for covering the interspace (26) and for sealing are necessary.Type: GrantFiled: December 18, 2001Date of Patent: September 7, 2004Assignee: Vetrotech Saint-Gobain (International) AGInventors: Horst Seidel, Jan Strejcek, Simon Frommelt, Klaus Wildenhain

Publication number: 20040170837Abstract: A flame retardant composition includes a polymeric base material, a non-halogenated flame retardant material and a synergist material present in a concentration of about 1 percent by weight of the composition. The synergist is substantially free from metal oxides. The flame retardant composition achieves a flammability rating of at least V-2 when tested in accordance with UL testing conditions.Type: ApplicationFiled: October 30, 2003Publication date: September 2, 2004Inventors: Chris A. Benson, Tilak R. Varma, Lawrence L. Lezon

Patent number: 6764971Abstract: The present invention is directed to a durable and imaged flame-retardant nonwoven fabric that can be used for flame-retardant apparel and other related applications. The fabric is formed by providing a precursor web consisting of a blend of melamine fibers and aramid fibers. The precursor web is hydroentangled on a three-dimensional image transfer device for formation of the fabric. The resultant fabric provides desirable air permeability and Thermal Protective Properties.Type: GrantFiled: March 2, 2001Date of Patent: July 20, 2004Assignee: Polymer Group, Inc.Inventors: Karl Dewayne Kelly, Thomas A. Hill, Francois Lapierre, Spiro De Luca, Sergio Diaz de Leon
