The present application relates to a thermally expandable composition which contains at least one peroxidically cross-linking polymer, at least one peroxide, at least one blowing agent and at least one wax, to molded bodies containing said composition, and to a method for sealing and filling voids in components, for strengthening or reinforcing components, in particular hollow components, and for bonding mobile components, using molded bodies of this type.
FIRE-RESISTANT, FIRE RETARDANT AND/OR THERMAL INSULATION
An open cell foam, and particularly aerogels or other foams, having an inorganic, hydraded phase change material (PCM) embedded within pores or cells or a network within the foam have fire retardant, fire resistant and thermal insulating properties. These composite materials are preferably monolithic in character, and are mechanically robust allowing for example the attachment of nails or screws. With the PCM distributed throughout the open cell foam, the composite material has a wide array of applications including providing thermal, fire resistant, and fire retardant uses in battery containers, in automotives and other vehicles, etc.
Heat-insulating wall, and heat-insulating housing and method for producing the same
A heat-insulating housing (21) includes: a wall body; and an open-cell resin body (4) of thermosetting resin with which a heat-insulating space formed by the wall body is filled by integral foaming, the open-cell resin body including: a plurality of cells (47); a cell film portion (42); a cell skeleton portion (43); a first through-hole (44) formed so as to extend through the cell film portion; and a second through-hole (45) formed so as to extend through the cell skeleton portion, wherein the plurality of cells communicate with one another through the first through-hole and the second through-hole.
Air-permeable sponge composition and method for preparing air-permeable sponge by using the same
An air-permeable sponge composition and a method for preparing an air-permeable sponge by using the same belong to the field of articles for daily use. An air-permeable sponge composition includes a sponge body and an air-permeable coating, and an outer surface layer of the sponge body being coated with the air-permeable coating. A method for making the air-permeable sponge utilizes the composition of the air-permeable sponge, wherein the air-permeable sponge is made from the air-permeable sponge composition under specific process parameters. The sponge body and air-permeable coating have the same or similar contents of isocyanate, polyether polyol and polymeric polyol and a similar porous structure.
VISCOELASTIC POLYURETHANE FOAM WITH COATING
A coated viscoelastic polyurethane foam includes a viscoelastic polyurethane foam having the coating thereon, the viscoelastic polyurethane foam having a resiliency of less than or equal to 20% as measured according to ASTM D3574, and a coating material on and embedded within the viscoelastic polyurethane foam, the coating material including an aqueous polymer emulsion and an encapsulated phase change material.
In-situ gelatinous triblock copolymer elastomers in latex foams
Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.
Polyurethane Gel Particles, Methods and Use in Flexible Foams
Combinations of open cell flexible foams with polyurethane gel particles, and methods of making the combinations are described using a variety of procedures. The open cell flexible foam may partially or wholly comprise polyurethane foam and latex foam.
