Patent number: 5527599Abstract: Non-asbestos flexible sheet material suitable for use in gaskets (e.g., automobile exhaust manifold gaskets) operating at high temperature (e.g., 500.degree.-700.degree. C.) is made by impregnating a non-woven tissue of glass or like fiber stable at 700.degree. C. with an aqueous slurry of inorganic filler, particularly a clay, said aqueous slurry including a dispersed elastomeric binder (e.g., an acrylic) and a dispersed or dissolved binder (e.g., colloidal silica) which is essentially inorganic and is effective above 300.degree. C. The impregnated tissue is then dried.Type: GrantFiled: May 24, 1994Date of Patent: June 18, 1996Assignee: T&N Technology LimitedInventors: David G. Hall, Jonathan R. Kennerley

Patent number: 5503849Abstract: Provided is a conductivized cellulosic sheet material and a method for making the same. The conductivized sheet material comprises a fibrous matrix of cellulosic material and conductive clay intimately and uniformly dispersed throughout the cross-sectional thickness of the fibrous matrix. Such a conductivized sheet exhibits advantageously low volume and surface resistivities at high and low relative humidities.Type: GrantFiled: August 27, 1992Date of Patent: April 2, 1996Assignee: Otis Specialty Papers Inc.Inventor: Wayne L. Bilodeau
