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).

Foam compositions are provided including a polylactic acid polymer; second (e.g., polyvinyl acetate) polymer having a glass transition temperature (T.sub.g) of at least 25° C.; and plasticizer. Also described are articles comprising the foam compositions, such as a sheet or hearing protection article. Methods of making and using the foam compositions are further described herein.

A yellowing-resistant thermoplastic polyurethane (TPU) foam material and a preparation method thereof are provided. The yellowing-resistant TPU foam material includes a TPU prepared by subjecting an aliphatic diisocyanate, a chain extender, a polyol, an antioxidant, an ultraviolet (UV) absorber, and a UV light stabilizer to a reaction, where the TPU has a softening point of 90° C. to 160° C., a Shore hardness of 40 A to 98 A, and a melt index of 5 to 250 g/10 min. The prepared yellowing-resistant TPU foam material has excellent yellowing resistance, controllable foaming density, and uniform foam cell size.

Formulated polyol compositions include a non-halogenated polyol, a halogenated polyol, a phosphorus-containing flame retardant, an HFO and/or HCFO blowing agent and certain urethane catalysts. The compositions exhibit excellent storage stability. Foams made from the formulated polyol compositions have unexpectedly improved fire performance, as indicated by certain fire tests.

The present invention relates to preparations having improved efficacy as flame retardants, to the use thereof and to polyurethanes containing the preparations according to the invention.

A battery module comprising an electric cell and a potting compound associated with the electric cell. The potting compound is formed of a flame retardant component; a first component having an isocyanate reactive compound and water; and a second component having an isocyanate compound. The potting compound is a foam.

A process for preparing a porous material involves at least the steps of providing a mixture (I) containing a composition (A), which contains components suitable to from an organic gel, and a solvent (B); reacting the components in the composition (A) in the presence of the solvent (B) to form a gel; and drying of the gel. The composition (A) contains a catalyst system (CS), which contains at least a catalyst component (C1) selected from ammonium salts and phosphonium salts, and an acid with a phosphor containing acid group as a catalyst component (C2). Porous materials can be obtained in this way and the porous materials can be used as thermal insulation material and in vacuum insulation panels and vacuum insulation systems, in particular in interior or exterior thermal insulation systems as well as for insulation of refrigerators and freezers and in water tank or ice maker insulation systems.

The flame retardant foam is a molded form of a mixture containing at least a cellulose containing powder, a hydrophilic polymer, a foamable thermoplastic resin, a flame retardant, and water. The mixture contains at least one of tricalcium phosphate or silica as a dispersant.
