A laminate 10 includes: a foamed polyurethane layer 11 obtained from a foamable polyurethane resin composition containing an active hydrogen group-containing tin ricinoleate and a phosphorus-containing solid flame retardant; and a coating layer 15 adhered to the foamed polyurethane layer 11 by a polyurethane hot melt adhesive 13 containing a polyurethane prepolymer (I) obtained by using a polyol component (A) and a polyisocyanate component (B) as raw materials, and a catalyst (II).

Provided herein is a one-component polyurethane adhesive composition showing excellent adhesive strength on both press bent frit glass surfaces and painted metal surfaces.

Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are formed into an emulsion that includes a polyether containing oxyethylene groups, a nonionic surfactant and certain fumed silica, carbon black or talc particles.

The present invention provides a laminate 10 including: a foamed polyurethane layer 11 obtained from a foamable polyurethane resin composition containing an active hydrogen group-containing tin ricinoleate and a phosphorus-containing solid flame retardant; and a coating layer 15 adhered to the foamed polyurethane layer 11 by a polyurethane hot melt adhesive 13 containing a polyurethane prepolymer (I) obtained by using a polyol component (A) and a polyisocyanate component (B) as raw materials, and a catalyst (II).

Pest-resistant polyurethane spray foam formulations and products, including building insulation, are described. The “B” side of the formulation comprises water; a polyol composition comprising one or more polyols selected from glycerin-sucrose polyols, Mannich polyols, and aromatic polyester polyols, catalyst(s); surfactant(s); a blowing agent; and 0.5 to 5 wt.%, based on the amount of spray foam formulation, of a composition comprising a capsaicin compound. Capsaicin compounds can be successfully incorporated into spray foam formulations that process well to give high- quality foams. The foams inhibit termite infestation and can help to minimize or avoid structural damage that might otherwise go undetected.

Provided is a material having an excellent sound-absorbing performance which can be easily applied to the desired area at the operation site and which can effectively prevent sound leakage.

The material includes an open-cell soft polyurethane foam prepared from a 2-part reactive urethane resin composition prepared from a polyisocyanate component and a polyol-containing component, wherein the polyol-containing component comprises a polyol component, catalysts, a foam stabilizer, an amine compound having primary or secondary amino groups, and carbon dioxide; wherein an average sound absorption coefficient of said polyurethane foam is 30% or more, measured in accordance with JIS A 1405-2:2007 for 63 hertz to 5000 hertz; and the length of liquid-dripping is within 300 mm.

Recovery time and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 10,000 centipoise at 25° C., having a glass transition temperature of at most 15° C. and being inert to other components of the foam formulation.

A polyurethane microcellular elastomer, a non-pneumatic tire and a preparation process and use thereof are provided. The polyurethane microcellular elastomer is obtained from a polyurethane reaction system comprising components such as isocyanate, trimethylolpropane-started polycaprolactone triol, a catalyst and a foaming agent. The non-pneumatic tire produced from the polyurethane microcellular elastomer has very strong fatigue resistance and can be used for non-motor vehicles running at high speed.

This invention relates to odor control molecules comprised of polyethyleneimine compounds containing N-halamine and derivatives thereof.

The present invention provides a stabilising composition, comprising: a) a first phenolic antioxidant comprising one or more phenolic compounds having the structure of formula (I):

##STR00001##  wherein R.sub.1 is a linear or branched alkyl group having from 12 to 20 carbon atoms; and b) one or more second phenolic antioxidants independently selected from:  a mono-hydroxybenzene having lower steric hindrance than the first phenolic antioxidant;  a di-hydroxybenzene; and/or  a tri-hydroxybenzene.
