Patent number: 8057583Abstract: A method of improving filtration efficiency of a fibrous nonwoven filter media comprises providing a filter media and incorporating in the filter media one or more additives selected from the group consisting of silicone additives, wax additives, and mixtures thereof. The filter media comprises glass fibers, polymer fibers, and optionally binder. Inclusion of silicone and/or wax additive(s) in a filter media has surprisingly been found to increase filtration efficiency, for example, by 10-15%.Type: GrantFiled: August 7, 2008Date of Patent: November 15, 2011Assignee: Johns ManvilleInventors: Dale Addison Grove, III, Alan Michael Jaffee, Richard Thomas Giovannoni

Patent number: 7547375Abstract: Making mats using glass fibers having a diameter of about 13+/?3 microns, bound with a binder formed from a homopolymer or a copolymer of polyacrylic acid and a polyol produces fibrous nonwoven mats having high tensile strength and also an unexpected high flame resistance considering the amount of oxygen in the binder. Mats of the present invention pass the National Fire Protection Association's (NFPA) Flammability Test. Tabor stiffness of these mats is greater than about 40, preferably greater than about 50 and most preferably greater than about 55. Air permeability of the mats is preferably within the range of about 500 to about 800 CFM/sq. ft.

Patent number: 7462259Abstract: New coated nonwoven fibrous mats having properties particularly suited for a facer on gypsum wallboard and other substrates and in laminates of various types, and the method of making the coated mat is disclosed. The mat preferably contains a major portion of glass fibers and a minor portion of a resinous binder. The coating is preferably permeable and reduces fiber dust and abrasion experienced in the past with relatively coarse, relatively inexpensive glass fibers in the mat. Contrary to previous coating methods, the coated fibrous mat is made in-line on a wet mat forming production line by applying a wet foam binder onto a wet, fibrous web followed by drying and curing in-line.Type: GrantFiled: October 14, 2004Date of Patent: December 9, 2008Assignee: Johns MnavilleInventors: Richard Emil Kajander, Alan Michael Jaffee, Glenda B.
