  • Publication number: 20240301174
    Abstract: The present disclosure is directed to self-extinguishing aliphatic polyketone compositions suitable for direct or indirect contact with food and method of preparing same. The compositions and methods demonstrate an inverse synergistic effect between the composition's melt viscosity and a minimum amount of magnesium hydroxide to provide the composition with a self-extinguishing performance.

  • Publication number: 20230416002
    Abstract: A conveyer module, small fragments of which are detectable by X-ray and magnetic sensors, is formed from a compounded mixture of a thermoplastic polymer and a ferrous metal powder. The thermoplastic polymer comprises a polyketone constituting less than 85% by weight of the mixture. The ferrous metal powder is a 400 series stainless steel constituting between 16% and 20% by weight of the mixture.

  • Publication number: 20220002517
    Abstract: A conveyer module, small fragments of which are detectable by X-ray and magnetic sensors, is formed from a compounded mixture of a polyketone, stainless steel powder, and barium sulfate powder. The thermoplastic polymer comprises a polyketone constituting less than 95.5% by weight of the mixture. The stainless steel constitutes at least 0.5% by weight of the mixture, and the barium sulfate constitutes at least 4% or more by weight of the mixture.

  • Patent number: 5247004
    Abstract: Polymeric-containing compositions having improved oxidative stability have the polymer and at least two stabilizing agents. The composition can be a coating composition for substrates including those like fibrous material including fibers, bundles of fibers, strands, roving, flakes and beads. The composition can be present as a dried residue on the substrate. For Fibrous substrates, the composition also has at least one organofunctional silane coupling agent, may also have processing aids such as epoxy polyester polymers and/or lubricants. In addition, the polymeric-containing composition can have a crosslinking agent in an effective amount to produce a dried residue of limited swellability from the composition.

  • Patent number: 5085938
    Abstract: Chemically treated fibers have an aqueous chemical treating composition and are useful for reinforcing thermoplastic polymers most notably polyacetals and polyphenylenesulfide. The aqueous chemical treating composition has a water soluble silylazide in an effective coupling agent amount, and one or more stabilizing agents selected from a fortified film forming polymer present as an oil-in-water emulsion, an unsaturated organo-compound present in an amount to stabilize the reinforced matrix polymer from degradation by silylazide derivatives or additives, a water soluble polymer, like poly(vinyl alcohol) or silylated poly(vinyl alcohol) present in the composition in an amount greater than 10 weight percent of the composition and mixtures thereof, and water in an effective amount for application of the composition to the fibers.
