  • Roofing underlayment with enhanced walkability and traction
    Patent number: 11268281
    Abstract: A roofing underlayment with enhanced walkability and/or traction is provided. The roofing underlayment includes a base layer, a first coating layer adhered to a first surface of the base layer, and a melt-blown nonwoven layer adhered to the first coating layer. The melt-blown nonwoven layer enhances walkability by providing a rough surface on which roofing installers may walk.
    Type: Grant
    Filed: June 23, 2020
    Date of Patent: March 8, 2022
    Assignee: Owens Corning Intellectual Capital, LLC
    Inventors: Martin Vido, Zhenchao Sun, Jason Woodall, Stephanie Pruzinsky, Steve Thaxton, Sabrina DiFilippo, Chris Robinson

  • OXYGEN CARRYING MATERIALS AND METHODS FOR MAKING THE SAME
    Publication number: 20180221859
    Abstract: A method for producing an oxygen carrying material may include forming a mixture that includes powders of active mass precursor, support material precursor, and inert structure precursor, and producing the oxygen carrying material by heating the mixture at a temperature of greater than 1300° C. for a time sufficient to sinter the inert structure pre-cursor to form a high-strength inert structure. The inert structure precursor may be one or more refractory ceramic components.
