DIRECT ALKOXYLATION OF BIO-OIL
An alkoxylated bio-oil composition is provided. The alkoxylated bio-oil composition may include an alkoxylated bio-oil prepared from an alkoxylation of dewatered bio-oil. A method for preparing an alkoxylated bio-oil composition is provided. A copolymer composition is provided. The copolymer composition may include an alkoxylated bio-oil copolymer unit. A method for preparing a copolymer composition is provided.
Flexible polyurethane foam with suspended particles
The present disclosure describes a flexible polyurethane foam having suspended within its matrix particles of silicon dioxide, SiO.sub.2. The particles of silicon dioxide are interspersed within the polyurethane matrix and protrude from the surface of the foam. These particles form an abrasive surface and the produced foam finds use as a cleaning material. The foam includes the use of a pre-polymer polyol formed by the reaction of triol polyol having a molecular weight of from 700 to 8000 with a polyisocyanate and a tin catalyst. The produced foam is much more durable than commercially available melamine foams and is an effective cleaning foam.
Foam insulation with enhanced fire and smoke performance
A polyisocyanurate foam insulation product includes polyisocyanurate foam produced from reacting an isocyanate and a polyol blend having a functionality of at least 2.2. The isocyanate and the polyol blend are reacted so that the polyisocyanurate foam has an isocyanate index equivalent with or greater than 300. The polyisocyanurate foam includes a fire retardant and includes between 0.02 and 0.45 weight percent of a zinc salt compound. The foam insulation board exhibits a flame spread of no greater than 25 and a smoke index of no greater than 50 when exposed to flame conditions in accordance with an ASTM E-84 test.
POLISHING PAD EMPLOYING POLYAMINE AND CYCLOHEXANEDIMETHANOL CURATIVES
A chemical-mechanical polishing pad comprising a thermosetting polyurethane polishing layer includes an isocyanate-terminated urethane prepolymer, a polyamine curative, and a cyclohexanedimethanol curative. The polyamine curative and the cyclohexanedimethanol curative are in a molar ratio of polyamine curative to cyclohexanedimethanol curative in a range from about 20:1 to about 1:1.
Direct alkoxylation of bio-oil
An alkoxylated bio-oil composition is provided. The alkoxylated bio-oil composition may include an alkoxylated bio-oil prepared from an alkoxylation of dewatered bio-oil. A method for preparing an alkoxylated bio-oil composition is provided. A copolymer composition is provided. The copolymer composition may include an alkoxylated bio-oil copolymer unit. A method for preparing a copolymer composition is provided.
Spray foams containing non-halogenated fire retardants
A spray foam formulation used to form a spray foam insulation layer in a wall structure is described. The formulation may include the reaction product of a polyisocyanate compound and a polyol compound; a fire retardant chosen from at least one of a non-halogenated fire retardant; and a reactive halogen-containing fire retardant, and a carbohydrate. The spray foam insulation layer has an insulative R value of 3.0 to 7.2 per inch, and a density of between about 0.3 to about 4.5 pcf. Further, spray foam insulation made from the spray foam formulation may have fire retardant characteristics that are equivalent to or better than a similar spray insulation foam insulation using non-reactive halogenated fire retardants such as tris(1-chloro-2-propyl)phosphate (TCPP).
POLYESTER POLYOL COMPOSITIONS CONTAINING HFO-1336MZZM (Z)
Blends, polyol premix compositions, methods of forming such compositions, foamable compositions using the premix compositions, methods of preparing foams containing the premix compositions, and foams made using the premix compositions are described. The polyol premix composition includes a polyester polyol; halogenated olefin blowing agent; and a distribution-enhancing component. In the polyol premix composition, the blowing agent, the polyester polyol, and the distribution-enhancing component form a substantially uniform composition.
