Patent number: 6610756Abstract: An inorganic/organic composite foam that has a foam structure obtained from a combination of a phosphoric acid compound and/or a sulfuric acid compound with a blowing agent therefor, has reduced brittleness due to a cured material of an urethane prepolymer having NCO groups, and contains a powdery boric acid compound, and a process for producing the same. The foam is not only reduced in brittleness but also improved in foam strength after combustion due to the incorporation of the powdery boric acid compound while retaining inherent foam properties and inherent low quantities of heat of combustion and smoking in combustion. It is used in exterior wall panels, heat insulating materials, sound insulating materials, fireproof covering materials, lightweight aggregates, filling materials for cavities, and the like, which are required to have fire-proofing performance.Type: GrantFiled: December 30, 1999Date of Patent: August 26, 2003Assignee: Sanyo Checmical Industries, Ltd.Inventors: Tomokazu Shimizu, Tadaaki Yamazaki, Shinzo Kaida, Tsuyoshi Tomosada

Patent number: 6579911Abstract: Extruded, substantially closed-polystyrene foams that exhibit improved fire resistance yet contain lower levels of brominated fire retardant are disclosed. Methods of preparing the foams, comprising extruding the polystyrene with a novel fire retardant formulation comprising a mixture of a) a phosphate compound, preferably TPP; b) less than about 2.5 percent HBCD based on 100 percent polystyrene; and optionally c) a flow promoter such as dimethyldiphenylbutane, the extrusion process using a blowing agent which is preferably selected from carbon dioxide, mixtures of two or more of carbon dioxide, water, alcohol, ether and hydrocarbons, or a mixture of hydrofluorocarbons, alcohols, and hydrocarbons, are also disclosed. Use of the phosphate compound in the fire retardant formulation allows a reduction in the amount of brominated compound required and a reduction in the foaming temperature, resulting in lower density foams.Type: GrantFiled: June 4, 2001Date of Patent: June 17, 2003Assignee: The Dow Chemical CompanyInventors: Chau Van Vo, Sylvie Boukami
