  • Patent number: 11441721
    Abstract: A damper that is made up of a number of dampening members that have a flexible core that is covered with an arctic grade rubber cover. Each dampening member is then attached to links that make up the damper chain. The steel core is made of steel wire that is fitted with a bolt at each end. The cover is placed over the steel core and is then sealed with end covers that are glued in place. Each end cover has a hole to receive a fastener that first passes through a link and then into the bolt at the end of the steel core. In this way, a strong, yet flexible damper chain is formed that is able to stand up to the harshest weather conditions for a long life.

    Abstract: Disclosed are a fluorine-silicon-containing polyphosphate ester and method for preparation thereof, having a chemical structural formula of: wherein R1 is R2 is n=10˜100. The fluorine-silicon-containing polyphosphate ester of the present invention uses silicon phosphorus and fluorine for improving flame retardancy. Phosphorus catalyzes the system to form a phosphorus-rich carbon layer, performing a protective-layer function and thereby preventing further breakdown of the epoxy resin. The silicon-containing epoxy resin forms a silica-containing carbon layer during the process of combustion, strengthening the carbon-layer structure and further improving the protective function of the carbon-layer. The introduction of elemental fluorine improves the thermal stability of the epoxy resin, thereby improving the flame retardancy performance of the system.

After injection of the composition into the medium, the one or more dormant functional groups and/or one or more pendent crosslinkable groups may be activated, and the polymer may be crosslinked. In certain cases, the crosslinked polymer may be removed from the medium to produce a freestanding three-dimensional structure.

  • Patent number: 10808079
    Abstract: Various embodiments provide random copolyimides that may possess the mechanical, thermal, chemical and optical properties associated with polyimides yet achieve a low energy surface. In various embodiments, the copolyimides may be prepared using a minor amounts of a diamino terminated fluorinated alkyl ether oligomer and a diamino terminated siloxane oligomer. The various embodiments include processes for making the copolyimides containing fluorine and silicon surface modifying agents and anisotropic coatings and articles of manufacture from them. Thus the coatings and articles of manufacture made with the copolyimides of the various embodiments may be characterized as having an anisotropic fluorine and silicon composition and low surface energy.
