| 20080306175 | Trans-1,2 Dichloroethylene Composition - The present invention relates to a composition based on trans-1,2-dichloroethylene. A subject-matter of the invention is more particularly a nonflammable composition comprising trans-1,2-dichloroethylene and at least two hydrofluorocarbons and its uses. | 12-11-2008 |
| 20110015288 | POLYMER FOAMS - A process for producing polymer foams by precise control of their morphology through use of microfluidic processes, foams produced in this way and use thereof. | 01-20-2011 |
| 20110190408 | CATALYSIS OF NATURAL OIL BASED FLEXIBLE POLYURETHANE FOAMS WITH BISMUTH COMPOUNDS - A process for producing a polyurethane product comprises steps of (a) supplying at least one polyisocyanate (b) supplying at least one polyol composition comprising at least about 5 weight percent based on total weight of polyols of at least one natural oil based polyol (b1) having a hydroxyl number of at most about 300 and a viscosity below about 10000 mPa·os; and (c) exposing the polyisocyanate and the polyol composition to reaction conditions such that urethane bonds are formed, wherein reaction conditions include the presence of at least one bismuth catalyst. Use of bismuth catalysts is particularly applicable to preparation of open celled, flexible polyurethane foams using polyols made from renewable resources, optionally with other polyols. The invention includes foams made by the process, including viscoelastic foams, preferably having a velvet feel. | 08-04-2011 |
| 20110190409 | LADDER POLYMERS WITH INSTRINSIC MICROPOROSITY AND PROCESS FOR PRODUCTION THEREOF - A polymer of formula (I): where: n is an integer from 10 to 5,000; m is an integer from 10 to 5,000; Ar1 and Ar3 are the same or different and are residues derived from a tetra-hydroxy aromatic monomer, the tetra-hydroxy aromatic monomer being wherein R is the same or different and is H or a C | 08-04-2011 |
| 20120220677 | Polyurethane Foam Premixes Containing Halogenated Olefin Blowing Agents And Foams Made From Same - The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a non-amine catalyst used alone or in combination with an amine catalyst. | 08-30-2012 |
| 20150299373 | METHOD FOR PRODUCING SOFT POLYURETHANE FOAM BASED ON POLYESTER POLYOLS - The present invention relates to a process for the production of flexible polyurethane foams, wherein there is used as starting material a polyester polyol component which is composed of at least two dicarboxylic acids. | 10-22-2015 |
