  • 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
