20110039968 | POLYURETHANE ELASTOMERS FROM RENEWABLE RESOURCES - A process is disclosed for preparing a elastomer by contacting under reaction conditions: a) an isocyanate component comprising an isocyanate-terminated prepolymer having an isocyanate (NCO) content of 10 to 30 weight percent where the prepolymer is the reaction product of a stoichiometric excess of one or more di- or poly-isocyanate compounds, collectively referred to hereinafter as isocyanate component, with a first polyol component; b) a second polyol component; and c) an effective amount of a blowing agent to provide a polyurethane elastomer with a density of from 200 to 1200 kg/m | 02-17-2011 |
20130202891 | ELASTOMER BINDING MATERIALS MADE WITH NATURAL OIL BASED POLYOLS - Embodiments of the invention provide for polyurethane binders or adhesives that result in an increased amount of renewable resources in the final composite products while yet maintaining the quality of the composite products. | 08-08-2013 |
20140128488 | Method for Making Organic Foam Composites Containing Aerogel Particles - Aerogel particles are impregnated with a volatile liquid. Organic polymer foams are made in the presence of the impregnated aerogel particles. The volatile liquid volatilizes during the foaming process, resulting in a composite foam in which the dispersed aerogel particle are filled with gas. The composite foams have exceptionally low thermal conductivities. | 05-08-2014 |
20140212619 | PANEL WITH FIRE BARRIER - A panel with fire barrier comprises: a metal facing; an insulating foam layer; and at least one fire barrier layer between the metal facing and the foam layer, the fire barrier layer(s) comprising at least one of porous silica; hollow glass microspheres; glass fibres; an inorganic ceramifying composition; a dispersion in a polyurethane polymer matrix or polyurethane/polyisocyanurate polymer matrix or polyurethane/polyurea polymer matrix of expandable graphite. A panel arrangement with fire barrier material in the joint regions between panels, methods of forming the panel and panel arrangement, fire barrier compositions, and reactants for forming the fire barrier compositions are also described. | 07-31-2014 |
20140329079 | FIRE RESISTANT COMPOSITE STRUCTURE - The present invention relates to fire resistant composite structures. As an example, a fire resistant composite structure can have a foam material located between a first facing and a second facing, and a barrier layer on the foam material. The barrier layer can include an adhesive material and a heat absorption material, where the heat absorption material has a melting point of 40° C. to 140° C. and is 15 weight percent to 99 weight percent of the barrier layer. | 11-06-2014 |
20150050486 | GEOPOLYMER PRECURSOR-AEROGEL COMPOSITIONS - Geopolymer precursor-aerogel compositions. As an example, a geopolymer precursor-aerogel composition can include an aluminosilicate reactant, an alkaline activator, an aerogel additive, and a continuous medium. | 02-19-2015 |
20150079367 | FIRE RESISTANT COMPOSITE STRUCTURE - Fire resistant composite structures. As an example, a fire resistant composite structure can have a foam material, a geopolymer thermal protection layer adhered to the foam material, and a facing adhered to the geopolymer layer. The geopolymer thermal protection layer can be formed by curing geopolymer precursors having a silicon to aluminum ratio in a range of 1.0:0.1 to 1.0:3.3. | 03-19-2015 |
