Patents by Inventor Christopher Thiede

Christopher Thiede has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12060506
    Abstract: Recovery times of flexible polyurethane foams are increased by treatment with a pressure sensitive adhesive. An emulsion or dispersion of the adhesive in an aqueous carrier liquid is impregnated into the foam, with subsequent removal of the carrier. This invention is of special interest when the glass transition temperature of the starting foam is 16° C. or lower.
    Type: Grant
    Filed: March 8, 2019
    Date of Patent: August 13, 2024
    Assignees: Dow Global Technologies LLC, Rohm and Haas Company
    Inventors: Kaoru Aou, William A. Koonce, Qinghao Meng, Christopher Thiede, William Griffith, Jr.
  • Patent number: 11912815
    Abstract: Flexible polyurethane foams having high airflows and excellent viscoelastic properties are made using a polyol mixture that includes a certain liquid polyester, certain ethylene oxide polyols and certain propylene oxide polyols, and a polymeric MDI. When used in applications such as bedding, the high airflows contribute to an improved sense of comfort by the user.

  • Patent number: 11401366
    Abstract: Recovery time and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 10,000 centipoise at 25° C., having a glass transition temperature of at most 15° C. and being inert to other components of the foam formulation.

  • Patent number: 11312809
    Abstract: Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 5,000 centipoise at 25 #C and having a glass transition temperature of at most 20 #C. The tackifier is pre-blended with certain monols to form a lower-viscosity blend that is combined with one or more other polyols and a polyisocyanate to form a reaction mixture for producing a polyurethane foam.

  • Patent number: 10450401
    Abstract: A reaction system for forming a polyurethane foam includes an isocyanate component that has at least one isocyanate and an isocyanate-reactive component that is a mixture formed by adding at least a polyol component, an additive component, and a preformed aqueous polymer dispersion. The mixture includes, based on the total weight of the mixture, from 50.0 wt % to 99.8 wt % of a polyol component including at least one polyether polyol, from 0.1 wt % to 50.0 wt % of an additive component including at least one catalyst, and from 0.1 wt % to 6.0 wt % of a preformed aqueous polymer dispersion. The preformed aqueous polymer dispersion has a solids content from 10 wt % to 80 wt %, based on the total weight of the preformed aqueous polymer dispersion, and is one of an aqueous acid polymer dispersion or an aqueous acid modified polyolefin polymer dispersion in which the polyolefin is derived from at least one C2 to C20 alpha-olefin.
