Patent number: 12098851Abstract: A composite article and a method for insulating an appliance are disclosed. In general, the appliance is selected from the group of major, domestic or household appliances (e.g. ovens, stoves, ranges, etc.). The appliance has a first surface that defines a heating cavity, and a second surface opposite the first surface. The composite article comprises a backing layer spaced from the first surface, and an insulating layer sandwiched between the second surface and the backing layer. The insulating layer reduces heat transfer from the heating cavity to the backing layer (e.g. during use of the appliance). The insulating layer comprises a foamed silicone. The foamed silicone can be one formed via a hydrosilylation-curable silicone composition, a condensation-curable silicone composition, or a combination thereof. The insulating layer may comprise a foamed room-temperature-vulcanizing (RTV) silicone.Type: GrantFiled: December 23, 2019Date of Patent: September 24, 2024Assignees: DOW BRASIL SUDESTE INDUSTRIAL LTDA., DOW GLOBAL TECHNOLOGIES LLCInventors: Rodnei M.

Patent number: 8785507Abstract: This invention relates to viscoelastic silicone rubber compositions that are the products of the reaction of: (a) a silanol-terminated polyorganosiloxane base; (b) a boron-containing crosslinking agent; and (c) a siloxane bond-forming crosslinking agent. In a viscoelastic silicone rubber composition of the invention some of the crosslinks, the siloxane crosslinks, are permanent and others of the crosslinks, the boron-containing crosslinks, are temporary. Because a fraction of its crosslinks can come apart and then reform, a viscoelastic silicone rubber composition of the invention can relax stress in response to strain and thus adapt to new shapes. The composition has sufficient permanent crosslinks, however, to establish a permanent equilibrium shape to which the composition will eventually return when not subject to any imposed stress.Type: GrantFiled: March 9, 2011Date of Patent: July 22, 2014Assignee: University of Virginia Patent FoundationInventor: Louis A.

Publication number: 20130210621Abstract: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor film is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids located adjacent to the discrete domains.Type: ApplicationFiled: February 10, 2012Publication date: August 15, 2013Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Vasily A.

Patent number: 7030168Abstract: Supercritical fluid-assisted deposition of materials on substrates, such as semiconductor substrates for integrated circuit device manufacture. The deposition is effected using a supercritical fluid-based composition containing the precursor(s) of the material to be deposited on the substrate surface. Such approach permits use of precursors that otherwise would be wholly unsuitable for deposition applications, as lacking requisite volatility and transport characteristics for vapor phase deposition processes.Type: GrantFiled: November 25, 2002Date of Patent: April 18, 2006Assignee: Advanced Technology Materials, Inc.Inventors: Chongying Xu, Thomas H. Baum
