20090105358 | SILICONE-CONTAINING FOAMS - Foamable, isocyanate-functional organopolysiloxanes with more uniform molecular weights are produced by reaction of an aminoalkyl or hydroxyalkyl functional organopolysiloxane with a stoichiometric excess of a di- or polysiocyanate in the presence of a compatibilizer which provides a homogenous reaction mixture. | 04-23-2009 |
20100267854 | POLYURETHANE FOAM CONTAINING SILICONE - Silicone-containing polyurethane foams of low density may be prepared from hyperbranched siloxanes. | 10-21-2010 |
20100286426 | METHOD FOR PRODUCING ISOCYANATE-TERMINATED SILOXANES - Isocyanate-functional or protected isocyanate-functional organopolysiloxanes are prepared directly by reaction of a siloxane bearing at least one silicon-bonded hydroxyl group with an alkoxy-functional α-silane containing an isocyanate group or blocked isocyanate group. | 11-11-2010 |
20100305226 | POLYURETHANE FOAM CONTAINING SILICONE - Silicone-containing polyurethane foams prepared from isocyanate-containing organosilicon compounds and expandable graphite are flame retardant without displaying liquifaction of the polymer component when the foam is exposed to high temperatures. | 12-02-2010 |
20110034574 | SILICONE-CONTAINING POLYISOCYANURATE FOAM - Silicone-containing polyurethane foams containing isocyanurate linkages are prepared from hyperbranched siloxanes having isocyanate groups or from hyperbranched siloxanes having isocyanate reactive groups and a polyisocyanate, the isocyanate groups being present in stoichiometric excess, in the presence of a trimerization catalyst. The foams are preparable at low densities and exhibit good flammability characteristics. | 02-10-2011 |
20110201712 | POLYURETHANE FOAM CONTAINING SILICONE - Low density, flame-retardant polyurethane foams are prepared by reaction of a polyisocyanate with a branched organopolysiloxane prepared by reaction of a reactive hydrogen-functional organopolysiloxane with a polyisocyanate followed by reaction with an amine. Water is preferably used as a blowing agent in a one shot process. | 08-18-2011 |
20130005847 | POLYURETHANE FOAM CONTAINING SILICONE - Silicone-containing polyurethane foams of low density, good pore structure, and high surface quality are prepared by reacting a branched, preferably hyperbranched silicone polyol with a polyisocyanate and a silicone resin in the presence of a reactive or non-reactive blowing agent. | 01-03-2013 |
20130072587 | SILICONE-CONTAINING POLYISOCYANURATE FOAM - Polyisocyanurate foams of closed cell structure and low density are obtained by reaction of an amino-functional hyperbranched organopolysiloxane polyol, polyisocyanate, trimerization catalyst, and blowing agent. | 03-21-2013 |
