  • Polyol premixes, thermally insulating rigid polyurethane foams and methods for their production
    Patent number: 11732100
    Abstract: Polyol premixes and thermally insulating rigid polyurethane foams, such as those that can be used as a thermal insulation medium in the construction of refrigerated storage devices, are disclosed. A polymer polyol having a OH number of greater than 260 mg KOH/g is utilized. The resulting polyurethane foams can exhibit improved thermal insulation properties without sacrificing other important physical and processing properties.
    Type: Grant
    Filed: July 1, 2022
    Date of Patent: August 22, 2023
    Assignee: Covestro LLC
    Inventors: Rick L. Adkins, Brandon W. Parks, Steve L. Aprahamian, Carson C. Miller, Emily E. Connor

  • RIGID POLYURETHANE FOAMS SUITABLE FOR USE AS PANEL INSULATION
    Publication number: 20220220249
    Abstract: Disclosed are polyurethane-foam forming compositions, rigid polyurethane foams and methods for their production, as well as to composite articles comprising such foams sandwiched between facer substrates, including use of such composite elements for side-wall and/or roof insulating elements for refrigerated tractor trailers. The rigid polyurethane foams are produced from an isocyanate-reactive composition comprising: (1) a polyol blend; (2) a hydrochlorofluoroolefin; and (3) a tertiary amine catalyst composition.
