Patents by Inventor Ali El-Khatib

Ali El-Khatib 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: 8372892
    Abstract: Polyurethane foams are made and attached to a substrate having an open cavity, but reacting prepolymer and polyol components in the presence of certain carbamate blowing agents. This process allows for very fast curing, good quality, adherent foamy to be produced on, for example, vehicle parts and assemblies, for acoustical or vibration dampening and for structural reinforcement.
    Type: Grant
    Filed: March 7, 2005
    Date of Patent: February 12, 2013
    Assignee: Dow Global Technologies LLC

  • Patent number: 7776934
    Abstract: Foamable one-part polyurethane compositions contain a high functionality quasi-prepolymer and a hydrated salt. The foamable compositions are capable of expanding to 1000% or more of their original volume to form a low density, stable foam. The compositions are particularly useful as foam-in-place thermal or sound insulation materials, especially in vehicle applications.

  • Publication number: 20070249743
    Abstract: Polyolefin compositions that expand freely to form stable foams are disclosed. The compositions include at least one heat-activated expanding agent and typically include at least one heat-expanded crosslinker. The compositions are effective as sealers and noise/vibration insulation in automotive applications.

  • Publication number: 20070128367
    Abstract: Foam-in-place, one component polyurethane compositions are useful to produce foams that adhere to various substrates such as certain vehicle parts and assemblies. The polyurethane composition contains a heat-activated blowing agent. The composition is based on a polyurethane resin that is expandable. The resin is a heat-softenable material, or a low molecular weight material that engages in further curing during the heat expansion step.

  • Publication number: 20050176839
    Abstract: Rigid polyurethane foams are described. The foams are made using a prepolymer that is the reaction product of at least one polyisocyanate component, at least one hydroxy-functional acrylate component, and at least one polyol component. The prepolymer is then reacted at specified volume ratios and isocyanate indices with at least one polyol component that includes at least one polyol that is a biopolymer, including but not limited to castor oil, soybean oil, and the like. The foam is made in the presence of at least one blowing agent and at least one catalyst.
