Articles useful for bedding and other comfort applications include a coated polyurethane foam. The coating includes an elastomeric polymer, a phase change material and ceramic particles. The coating provides desirable haptic properties, including a cool touch feature that creates a sensation of coolness when touched. The invention is also a coating composition for producing such a coating, and a method for producing the coating composition

Lightweight synthetic particles that replace traditional aggregates and methods of producing the same are disclosed herein.

The present invention relates to an acoustical and thermal decoupling system (10) in a form of a polymer tape that includes a closed-cell foam layer (12) having a front side and a reverse side, a pressure sensitive adhesive (14) coated on the reverse side of the closed-cell foam layer (12), and a release liner (16) covering the pressure sensitive adhesive (14) on the reverse side of the closed-cell foam layer (12). The acoustical and thermal decoupling system (10) may be installed directly to a structural member of a building by removing the release liner (16) from the reverse side of the closed-cell foam layer (12) and pressing the reverse side of the closed-cell foam layer (12) against the structural member, allowing the pressure sensitive adhesive (14) to bond the closed-cell foam layer (12) directly to the structural member.

The present disclosure is directed to articles that include one or more coated fiber(s) (i.e., fiber(s) with a cured coating disposed thereon), where the coating includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating is a product of crosslinking a coating composition including uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier, wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers). The present disclosure is also directed to articles including the coated fibers, methods of forming the coated fibers and articles, and methods of making articles including the coated fibers.

Polybutylene terephthalate can be used as a gas diffusion barrier for closed-cell rigid polyurethane foams. A thermal insulation element containing a closed-cell, rigid polyurethane foam, which is at least partially covered by a layer system containing at least one layer formed by a polybutylene terephthalate composition, is useful. Articles and devices may contain a corresponding thermal insulation structure, such as refrigerators, insulation panels, pipe insulations, water heaters, and thermally insulated transport boxes.

The present disclosure provides an article. The article includes a crosslinked foam composition, an adhesive layer, and a substrate composed of an olefin-based polymer. The crosslinked foam composition includes an ethylene/a-olefin multi-block copolymer, an ethylene/propylene/diene terpolymer (EPDM), optional silicone rubber, optional blend component selected from ethylene/aolefin random copolymer, ethylene-vinyl acetate copolymer (EVA), styrene-butadiene block copolymer, hydrogenated styrene-butadiene block copolymer, and combinations thereof, optional plasticizer, optional filler, and optional additive.

The present invention discloses a sound absorption material including an organic frame material; a binder; a thickener; and a plurality of sound absorption grains attached to the organic frame material via the binder, having a grain size in a range of 10-100 μm. The stability and the sound absorption performance of the sound absorption material have been effectively improved.

The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

There is provided a method of manufacturing an openly and highly porous thermoset foam, the method comprising the steps of mixing a thermosetting resin and crystals to form a mixture; applying pressure to the mixture to expel excess thermosetting resin, thereby producing a network of crystals touching each other with the thermosetting resin filling the interstices between the crystals of said network; curing the thermosetting resin in the mixture under pressure to produce a cured material; and contacting the cured material with a solvent for the crystals, thereby leaching the crystals out of the cured material, thereby obtaining said openly and highly porous thermoset foam. There is also provided a thermoset foam made of a thermoset and having a porosity of at least about 70%, wherein more than about 75% of the pores in the foam are connected to a neighboring pore.

Provided herein is a molded cellulose foam having a smooth, dense surface fiber layer and a low density, open-cell structure interior, a process for compression-molding fiber foam into such molded cellulose foam, articles prepared with such foam, and articles prepared by such process.
