Publication number: 20110086198Abstract: There are provided a foaming filler member which allows, even when the inner space of a hollow member has a protruding space, easy filling of the protruding space without using an extra member, a heat-foamable sheet used for the foaming filler member, a method for manufacturing the heat-foamable sheet, and a method for filling the inner space of the hollow member. A heat-foamable sheet which extends in one direction when heated at 100 to 130° C. for 20 minutes and has an extension ratio of 5 to 50% in the extension direction is manufactured by stretch-forming a heat-foamable material. Even when the inner space has the protruding space, the protruding space can be easily filled at low cost without using an extra member by using the heat-foamable sheet as the foaming filler member, disposing the foaming filler member in the main space of the inner space, and foaming it such that the extending direction of the heat-foamable sheet is oriented toward the protruding space.Type: ApplicationFiled: December 10, 2010Publication date: April 14, 2011Applicant: Nitto Denko CorporationInventors: Takehiro Ui, Yoshiaki Mitsuoka, Mitsuo Matsumoto

Patent number: 7923478Abstract: A nanoporous material is provided. The pores of the nanoporous material are formed between nanoparticles that have a polymeric surface layer. The nanoporous material is produced by (a) suspending the nanoparticles in a medium material, wherein the nanoparticles are phase separated from the medium material, (b) heating the suspension to a temperature above the melting point of the nanoparticle surface layer, and (c) cooling the suspension. Alternatively, the nanoporous material may be produced by dissolving nanoparticles having a polymeric surface layer in a solvent, and then adding a medium material that causes the nanoparticles to phase separate from the solution.Type: GrantFiled: December 12, 2007Date of Patent: April 12, 2011Assignee: Bridgestone CorporationInventors: Xiaorong Wang, Mindaugas Rackaitis

Patent number: 7906561Abstract: The invention pertains to a process for producing a cross-linked polyolefin foam in a continuous process using standard processing equipment without using a moisture cross-linking step after processing. In this method, a vinyl functional silane compound is melt grafted onto a low density polyethylene in the presence of a free radical generator. The resulting silane grafted polyethylene resin is mixed and melted with a blowing agent in a continuous process in the presence of water to form a vinyl functional silane foam.Type: GrantFiled: December 3, 2007Date of Patent: March 15, 2011Assignee: Ingenia Polymers, Inc.Inventors: Jianzhong Hu, Salvatore D'Uva, Arthur Tinson

Publication number: 20110060066Abstract: The present invention provides an emulsion composition for a vibration damper, which has heating and drying properties high enough to form an excellent coating film which can exhibit excellent damping without swelling during drying by heating, and an emulsion composition for a vibration damper, which can exhibit basic performances demanded in vibration dampers, in particular, markedly superior anti-sagging even under the condition of high humidity or a thick film where the coating film may sag in conventional technologies, and thus can be useful in vibration dampers of various structures. The emulsion composition for a vibration damper includes an emulsion obtainable by emulsion polymerization of monomer components, the emulsion composition containing 0.5 to 20% by mass of a film-forming agent with a weight average molecular weight of 100 to 20000 in 100% by mass of the emulsion composition.Type: ApplicationFiled: May 7, 2009Publication date: March 10, 2011Applicant: NIPPON SHOKUBAI CO, LTDInventors: Yoshiyuki Yokota, Yukihiro Miyawaki, Dai Nagaishi
