  • Physical properties improvement additive for flexible polyurethane foam
    Publication number: 20040006147
    Abstract: An exotherm reducing additive including a tetrahalogenated ionic compound and an exotherm reducing additive composition for organic polymer compositions including an exotherm reducing-effective amount of the tetrahalogenated ionic compound, a solvent for the tetrahalogenated ionic compound, and a diluent compatible with the tetrahalogenated ionic compound, the solvent and the organic polymer composition, The tetrahalogenated ionic compound preferably is a tetrahalogenated borate, and more specifically lithium or sodium tetrafluoroborate. Organic polymer compositions containing the additive also are provided, as are methods incorporating the additive into the polymer compositions.
    Type: Application

    Publication date: January 8, 2004
    Inventor: Dennis R. Spicher
  • Antistatic additives including tetrahalogenated ionic compounds for organic polymer packaging compositions
    Publication number: 20030158313
    Abstract: An antistatic additive includes a tetrahalogenated ionic compound. An antistatic additive composition for organic polymer compositions includes an antistatically-effective amount of the tetrahalogenated ionic compound, a solvent for the tetrahalogenated ionic compound, and a diluent compatible with the tetrahalogenated ionic compound, the solvent and the organic polymer composition. The tetrahalogenated ionic compound preferably is a tetrahalogenated borate, and more specifically lithium or sodium tetrafluoroborate. Organic polymer compositions containing the additive also are provided, as are methods incorporating the additive into the polymer compositions.

  • Antistatic additive for organic polymer compositions
    Patent number: 5955526
    Abstract: An antistatic additive including a hexahalogenated ionic compound, and an antistatic additive composition for organic polymer compositions including an antistatically-effective amount of the hexahalogenated ionic compound, a solvent for the hexahalogenated ionic compound, and a diluent compatible with the hexahalogenated ionic compound, the solvent and the organic polymer composition. The hexahalogenated phosphate compound is preferably either potassium hexafluorophosphate, sodium hexafluorophosphate, and ammonium hexafluorophosphate. Organic polymer compositions containing the additive also are disclosed, as are methods of manufacturing both the additive and the polymer compositions.
    Type: Grant
