| 20080207784 | Polyvinylchloride/polyurethane hybrid foams with improved burn properties and reduced after-glow - The present invention provides a rigid polyurethane foam comprising the reaction product, at an isocyanate index of from about 90 to about 400, of a polyisocyanate and a polyol component comprising, about 20 wt. % to about 80 wt. %, based on the weight of the polyol component, of a double metal cyamide (DMC)-catalyzed polyether polyol having a number average molecular weight of greater than about 1,000 Daltons (Da), about 80 wt. % to about 20 wt. %, based on the weight of the polyol component, of a sucrose-based polyol having a functionality of from about 2.5 to about 6 and a number average molecular weight of from about 350 Da to less than about 1,000 Da, and about 0 wt. % to about 40 wt. %, based on the weight of the polyol component, of a low molecular weight organic compound having a number average molecular weight of less than about 600 Da in the presence of water, polyvinylchloride (PVC) particles having a diameter of from about 0.1 microns to about 200 microns, glass beads having a diameter of from about 40 microns to about 400 microns, and about 1 wt. % to about 30 wt. %, based on the weight of the polyol component, of expanded graphite, optionally, in the presence of at least one of carbon dioxide, surfactants, flame retardants other than expanded graphite, crosslinking agents, pigments and catalysts, wherein the rigid polyurethane foam with a density of about 10 pcf to about 25 pcf has a heat sag measured at 102 mm overhang at 121° C. and one hour of less than about 5 mm and an average after-glow time of less than about 35 seconds. The inventive rigid polyurethane foams exhibit improved burn properties and reduced after-glow while maintaining improved heat sag performance over commercial materials. | 08-28-2008 |
| 20100137464 | POROSITY CONTROL WITH POLYHEDRAL OLIGOMERIC SILSESQUIOXANES - The use of nanostructured chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are used to control porosity in organic and inorganic media. The precisely defined nanoscopic dimensions of this class of chemicals enables porosity to be both created (increased) or reduced (decreased) as desired. The thermal and chemical stability of the POSS/POS nanostructures and the ability of these nano-building blocks to be selectively placed or rationally assembled with both inorganic and organic material mediums allow tailoring of porosity. | 06-03-2010 |
| 20120101175 | Silicone Copolymer Surfactants For Use In Polyurethane Foams - The present invention provides a novel silicone copolymer surfactant, methods for making the surfactant, a polyurethane foam-forming composition and a process for preparing polyurethane foams. | 04-26-2012 |
| 20120190760 | SILICONE-POLYETHER BLOCK COPOLYMERS WITH HIGH MOLECULAR WEIGHT POLYETHER RESIDUES AND THEIR USE AS STABILIZERS FOR PRODUCTION OF POLYURETHANE FOAMS - Silicone-polyether block copolymer comprising a polyorganosiloxane which includes at least one polyether residue having a molecular weight of not less than 5000 g/mol, and wherein a weight average molecular weight of all polyether residues attached to the polyorganosiloxane by a chemical bond is above 3000 g/mol, its production and use and also compositions and polymeric articles obtained therewith. | 07-26-2012 |
| 20120277335 | PUNCTURE RESISTANT LEAKLESS MATERIAL FOR TUBELESS TIRE AND ITS MANUFACTURING AND SPRAY COATING METHODS - The invention relates to puncture resistant leakless material for tubeless tire and its manufacturing and spray coating methods. The object of the invention is to provide a puncture resistant leakless material and its manufacturing and spray coating methods. The puncture resistant leakless material resists high temperature, low temperature, oil and water, has high leakproof property, costs low, and could keep running in a high speed for a very long time when a sharp object punched through, or when the sharp object in the tire. The puncture resistant leakless material has high tear resistance, resilience and long service life. When a sharp object punched through, or when the sharp object in the tire, tire using the material of the invention could keep running in a high speed for a very long time without leakage or dropping of pressure. The raw materials for manufacturing the puncture resistant leakless material for tubeless tire of the invention do not need vulcanization, which quite saves energy and costs during the manufacture. | 11-01-2012 |
| 20140024731 | SILICONE COMPOSITION FOR ELASTOMER FOAM - The present relates to novel organopolysiloxane compositions intended to generate an elastomer foam (or silicone foam) with good mechanical properties and low density low density, i.e. less than 0.35 g/cm3 and preferably less than 0.25 g/cm3. | 01-23-2014 |
| 20140107239 | METHOD FOR PRODUCING A FOAMED MATERIAL,COMPOSITION IN THE FORM OF AN EMULSION USED IN SAID METHOD, AND FOAMED MATERIAL THAT CAN BE OBTAINED FROM SAID METHOD - The present invention relates to a process for producing a foamed material, wherein a composition in the form of emulsion with a matrix-forming component, a surfactant component and a near-critical or supercritical blowing agent component is submitted to a lowering of pressure. The blowing agent component further comprises a hydrophobic co-component, which is soluble in supercritical CO | 04-17-2014 |
| 20150148437 | MINERAL-FILLED POLYPROPYLENE COMPOSITION FOR FOAMING - The present invention relates to a new polypropylene composition for the production of foamed molded articles, such as finished parts for the automotive industry. | 05-28-2015 |
