Patent number: 7371798Abstract: A thermoplastic water-curable composition which is excellent in mechanical properties, heat resistance, dimensional stability, and moldability and from which a mechanical part of a complicated shape can be produced: a molding formed from the thermoplastic water-curable composition; and a process for producing the molding. The thermoplastic water-curable composition comprises: a thermoplastic resin which upon contact with water undergoes a cross-linking reaction and thus comes to have a high molecular weight, desirably one having silane groups in inner parts thereof and a water-curable composition, the amount of water-curable composition being desirably 200 to 700 parts by weight per 100 parts by weight of the resin The molding is formed from the thermoplastic water-curable composition. The process comprises molding the thermoplastic water-curable composition into a given shape and then bringing the molding into contact with water to age and cure it.Type: GrantFiled: December 12, 2002Date of Patent: May 13, 2008Assignee: Sumitomo Osaka Cement Co., Ltd.Inventors: Satoshi Ozawa, Kouji Mikami, Shigefumi Hisatsune

Patent number: 7321009Abstract: The invention is concerned with gasket sealing foils having a sealing layer with enhanced properties which is based upon chemically exfoliated vermiculite. The method of producing a sealing foil for gaskets is described. The method comprises the steps of: (a) the application of a wet sealing foil material to a forming sheet to form a layer, (b) partially drying the said wet sealing foil layer on the forming sheet; (c) removing the said layer from the forming sheet to form a core free gasket sealing foil; and (d) forming, preferably cutting, the layer into at least one suitable shape for use in the formation of a gasket The sealing foil comprises a resilient material, which comprises a CEV component in a proportion of at least 25% w/w of the sealing foil, the CEV component being at least partially derived from dry CEV. The sealing foil layer may be combined with a gasket support layer prior to or after the cutting step.Type: GrantFiled: July 3, 2002Date of Patent: January 22, 2008Assignee: Flexitallic Investments IncorporatedInventors: John Robert Hoyes, Stephen Woolfenden
