Patent number: 6815047Abstract: A foamed thermoplastic resin sheet has a foaming ratio of not less than 2.5, and cells, existing in an interior part which extends inward from a depth of 20 percent a whole thickness of the sheet from the front and rear surfaces thereof respectively in a thickness direction thereof and from 15 percent a width of the sheet from both side edges respectively, satisfy the following expressions (1) and (2): 0.5≦D/C≦0.9 (1) 0.5≦E/C≦0.9 (2) where C represents a mean cell diameter in the thickness direction of the foamed thermoplastic resin sheet, D represents a mean cell diameter in an extrusion direction (MD) of the same, and E represents a mean cell diameter in the width direction (TD) of the same. The foamed thermoplastic resin sheet thus arranged has a high foaming ratio, and is formed thick.Type: GrantFiled: December 23, 1998Date of Patent: November 9, 2004Assignee: Sumitomo Chemical Company, LimitedInventors: Takeo Kitayama, Kaori Tsubouchi, Shigeyoshi Matsubara, Tatsuhiro Nagamatsu

Patent number: 6815048Abstract: Polymeric films including a layer of propylene polymer resin having microvoids therein, the microvoids having been formed by stretching a web containing the beta-form of polypropylene, have shown low static cling when being unwound from rolls in labelling operations and also during destacking of pre-formed labels. The invention provides labels formed from such films.Type: GrantFiled: August 6, 2002Date of Patent: November 9, 2004Assignee: Hoechst Trespaphan GmbHInventors: Paul Malcolm Mackenzie Davidson, Rebecca Karen Govier, Helen Ann Biddiscombe, Marc Fritz Manfred Ott

Patent number: 6815049Abstract: A composition including, but not limited to, a mixture of a calcium sulfate material, water, and a tetrametaphosphate compound is disclosed. Desirably, the inclusion of the tetrametaphosphate compound (e.g., salt or ion) in a pre-set treatment of a calcium sulfate material enhances the resistance to permanent deformation (e.g., sag), dimensional stability, and/or compressive strength of the composition while also preferably avoiding any significant retardive effect on the rate of hydration of calcined gypsum to calcium sulfate dihydrate. A set gypsum-containing product and a method for producing a set gypsum-containing product having increased resistance to permanent deformation are also disclosed.Type: GrantFiled: December 11, 2001Date of Patent: November 9, 2004Assignee: United States Gypsum CompanyInventors: Srinivas Veeramasuneni, Qiang Yu, William A.

Patent number: 6815051Abstract: A foam layer can be formed at a temperature at which the surface quality of a surface layer is not deteriorated, and a molding technique that is excellent in adhesiveness of a foam layer and a surface layer or/and a base member is developed. For the purpose of obtaining a resin molding composite, the present invention is characterized by a polyolefin resin molding composite comprising a surface layer and a foam layer, or a surface layer, a foam layer, and a base member, wherein the foam layer comprises a foam layer produced by fusion bonding thermoplastic expanded resin particles one another by molding, where the thermoplastic expanded resin particles comprises a core that is made of a crystalline thermoplastic resin and is in an expanded state and a polyethylene resin coat covering the core, and the surface layer comprises a thermoplastic synthetic resin having a melting point of 5° C. or more higher than a melting point of polyethylene resin constituting the coat of the particles.Type: GrantFiled: April 20, 2001Date of Patent: November 9, 2004Assignee: JSP CorporationInventors: Masaaki Yokoyama, Masahiro Tanaka
