Patent number: 7635724Abstract: To provide a flexible polyurethane foam having good vibration characteristics and suitable particularly for a seat for an automobile. A flexible polyurethane foam obtained by reacting a polyol composition with a polyisocyanate compound in the presence of a catalyst, a blowing agent and a foam stabilizer, characterized in that the polyol composition comprises a high molecular weight polyoxyalkylene polyol (A) and a polymer-dispersed polyol (C) containing fine polymer particles in a high molecular weight polyoxyalkylene polyol (B), and at least part of the fine polymer particles are fine polymer particles obtained by polymerizing a monomer containing a fluorinated acrylate or a fluorinated methacrylate.Type: GrantFiled: November 26, 2007Date of Patent: December 22, 2009Assignee: Asahi Glass Company, LimitedInventors: Takayuki Sasaki, Takashi Ito, Chitoshi Suzuki, Tomohiro Hayashi

Publication number: 20090312447Abstract: A resin blend composition is provided containing a polyol, an ethoxylate propoxylate surfactant initiated by a short chain compound, and a hydrocarbon blowing agent. The solubility and/or compatibility of the hydrocarbon carbon blowing agent in the polyol is increased and the phase stability of the resin blend composition is improved by the ethoxylate propoxylate surfactant. The resin blend is suitable for reaction with polyfunctional organic isocyanates to make cellular polyurethane and polyisocyanurate foams.Type: ApplicationFiled: February 15, 2006Publication date: December 17, 2009Applicant: Stepan CompanyInventor: F.

Publication number: 20090306236Abstract: The present invention provides a process for producing a rigid polyisocyanurate foam involving reacting at an isocyanate index of from about 175 to about 400, a polyisocyanate with at least one natural-oil polyol containing at least about 35 wt. %, based on the weight of the polyol, of natural oil, having a hydroxyl number from about 175 to about 375 and a hydroxyl functionality of about 2.0 to about 2.8, in the presence of a blowing agent and optionally, in the presence of one or more of surfactants, flame retardants, pigments, catalysts and fillers, wherein the resulting foam has a renewable biobased content of at least 8% by weight. The foams provided by the inventive process possess properties similar to foams produced from petroleum-derived materials and may find use in wall or roof insulation systems. The high biobased content (>8%) may allow wall or roof insulation systems containing these foams to be considered for the U.S. Government's preferred procurement program.Type: ApplicationFiled: June 4, 2008Publication date: December 10, 2009Applicant: BAYER MATERIAL SCIENCE LLCInventors: DAVID F. SOUNIK, Steven L. Schilling, Don S. Wardius, Edward E. Ball
