    Abstract: Disclosed is a thermoplastic resin foam which excels typically in strength, flexibility, cushioning properties, and strain recovery and is especially resistant to cell structure shrinkage caused by the restoring force of resin. The thermoplastic resin foam which is obtained by subjecting a thermoplastic resin composition containing a thermoplastic elastomer and an active-energy-ray-curable resin to foam molding to give a foamed structure, and irradiating the foamed structure with an active energy ray to allow the active-energy-ray-curable resin to form a cross-linked structure in the foamed structure.

  • Publication number: 20100147760
    Abstract: A filter assembly for removing contaminants from a fluid includes a filter housing, a filter cartridge, and a reticulated foam fluid treatment media. The filter housing has an inlet, an outlet and a chamber extending through the filter housing. The filter cartridge is positioned in the chamber of the filter housing and is constructed from a fibrous material used to filter contaminants from a fluid. The reticulated foam fluid treatment media is disposed within a passageway of the filter cartridge. The reticulated foam fluid treatment media includes a porous polymeric substrate having surfaces, including pore walls, and particles secured to the surfaces of the porous polymeric substrate via a binder, the particles being substantially uniformly distributed throughout the porous polymeric substrate via sonic vibration of the porous polymeric substrate and particles.

  • Patent number: 7704437
    Abstract: A compounded rubber, which is made up of an NBR polymer, an organic peroxide and a blowing agent, to which 1 to 100 parts by weight of a synthetic silicic acid serving as a reinforcing filler and 10 to 200 parts by weight of precipitated calcium carbonate having a prismatic particle shape and serving as a filler are added to 100 parts by weight of the NBR polymer, is extrusion molded by a continuous extruder, and heated by HA heating and UHF heating in combination throughout the rubber to cause vulcanization and expansion, thereby providing a thick sponge having a homogenous cell structure. The sponge is passed through press rolls, and the resulting sheet stock is cut or punched with a cutting or punching machine into pieces of a desired form to obtain an applicator for cosmetics.

  • Publication number: 20070264484
    Abstract: Process for continuous manufacture of latex foam rest articles such as mattresses, cushions and the like comprising a part able to participate to the manufacture steps and to remain embedded in the article with consequent improvements of final performances. A flexible perforated band, preferably a flat polymeric material net with longitudinal and cross reinforcement members, is placed over a foam laying surface provided with protuberances and in continuous advancement between a foam laying station and an unlimited length article extraction station. The latex foam passes through net holes forming an upper portion and a lower portion relative to said net. The net continuously opposes contraction forces and weight force exerted from upper portion on lower portion. The unlimited length article is subjected to successive cross cuts originating rest articles wherein a foam embedded net is arranged on ends of recesses originated by the protuberances.

  • Publication number: 20040198853
    Abstract: Carbon dioxide in a supercritical state is caused to permeate into a resin composition formed by sufficiently kneading a thermoplastic copolymer having a polysiloxane structure at recurring units. Subsequently, the resin composition is degassed by cooling and/or pressure reduction. As a result of degassing, a resin foam body 1 having a fine and uniform micro-cellular foam structure is obtained. The resin foam body 1 has a cyclic structure in which a resin phase 2 and a pore phase 3 are continuous and intertwined. The resin foam body 1 shows an excellent reflectivity relative to rays of light and is highly nonflammable, while it is very strong and lightweight.

  • Patent number: 6616886
    Abstract: Methods and apparatus for eliminating or reducing a surface skin when producing a flexible polyurethane foam slab are disclosed. The top surface of the chemically reactive polyurethane foaming mixture is heated during and/or after the foaming mixture expands. The heating preferably is conducted so as to prevent a significant temperature gradient from forming between the internal temperature of the foaming mixture and the top surface of that mixture. Preferably, heat is applied so as to heat from the top surface of the foaming mixture in an escalating fashion to higher temperatures as the foam is conveyed along a conveying path away from the foaming mixture dispensing device.
