Joachim FLOECK 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).

  • Low Noise Polymer Composition
    Publication number: 20230055930
    Abstract: A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer, reinforcing fibers, and at least one tribological modifier. The tribological modifier, in one embodiment, can comprise a graft copolymer. The use of a graft copolymer has been found to unexpectedly and dramatically improve noise generation when tested against various substrates, especially glass substrates.
