  • Acid Resistant Polyoxymethylene Composition and Articles Made Therewith
    Publication number: 20230183476
    Abstract: Polyoxymethylene polymer compositions and molded articles made from the composition are disclosed that are fuel resistant, particularly diesel fuel resistant, and resistant to highly acidic solutions. The polymer composition contains a polyoxymethylene polymer combined with a combination of stabilizers, such as a combination of at least three different stabilizers. In addition, the polymer composition contains an acid neutralizing agent and optionally a plasticizer.

  • Orthopedic device and polymer compositions for making same
    Patent number: 10912659
    Abstract: Orthopedic devices are described including polymer compositions used to make the devices. The polymer composition contains a polyoxymethylene polymer in combination with various additives that prevent against agglomerations and spotting even when the composition contains significant amounts of coloring agents and/or waxes. In addition, the polymer composition has reduced formaldehyde emissions and excellent thermal stability properties.
