  • Patent number: 8900491
    Abstract: A flame retardant filler having brominated silica particles, for example, imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. In this example, brominated silica particles serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. In an exemplary application, a PCB laminate stack-up includes conductive planes separated from each other by a dielectric material that includes a flame retardant filler comprised of brominated silica particles. In an exemplary method of synthesizing the brominated silica particles, a monomer having a brominated aromatic functional group is reacted with functionalized silica particles (e.g., isocyanate, vinyl, amine, or epoxy functionalized silica particles).

  • Patent number: 8888904
    Abstract: This invention describes the processes of formulating heat generating graphite-sodium silicate (G-S) coating agents/mixes, and coating these mixes on base layer boards/panels to construct moderate to high surface temperature heating devices that are environmentally safe, fire retardant, and economically viable. The core to such heating devices is the formulation of G-S coating agents/mixes that are composed of graphite, sodium silicate, and aluminum silicate. In these coating mixes, the graphite is the primary heat generating agent, the sodium silicate is the main fire resisting agent, and the aluminum silicate primarily serves as surface heat control and water proofing functions.
