  • Patent number: 6365071
    Abstract: The present invention relates to a synergistic flame retardant combination for thermoplastic polymers, preferably engineering plastics, especially for polyesters, which as component A comprises a phosphinic salt of the formula (I) defined in the description and/or a diphosphinic salt of the formula (II) and/or polymers thereof, and as component B comprises a nitrogen compound of the formula (III) to (VIII) defined in the description, or a mixture of the compounds represented by the formulae.
    Type: Grant
    Filed: January 29, 1999
    Date of Patent: April 2, 2002
    Assignee: Clariant GmbH

  • Patent number: 6270560
    Abstract: Salt mixtures made from aluminum phosphinates, aluminum hydroxide and/or aluminum phosphonates and/or aluminum phosphates are thermally stable and are suitable as flame retardants for polymeric molding compositions, in particular for polyesters and polyamides. The use of these salt mixtures is more effective and more cost-effective than the use of aluminum phosphinates alone.
    Type: Grant
    Filed: November 22, 1999
    Date of Patent: August 7, 2001
    Assignee: Ticona GmbH
    Inventors: Hans-Jerg Kleiner, Winfried Budzinsky
  • Patent number: 6087423
    Abstract: Salts of 1-hydroxydihydrophosphole oxides and 1-hydroxyphospholane oxides and use thereof as flame retardants. The salts of 1-hydroxydihydrophosphole oxides and 1-hydroxyphospholane oxides are useful as flame retardants, especially for plastics such as polyester or polyamide. The aluminum salts are preferred.

    Inventors: Hans-Jerg Kleiner, Winfried Budzinsky, Gunther Kirsch
  • Patent number: 6013707
    Abstract: Polyesters such as polyethylene terephthalate or polybutylene terephthalate are provided with a flame-retardant finish by addition of calcium salts or aluminum salts of phosphinic or diphosphinic acids.
    Type: Grant
    Filed: June 9, 1998
    Date of Patent: January 11, 2000
    Assignee: Ticona GmbH
    Inventors: Hans-Jerg Kleiner, Winfried Budzinsky, Gunther Kirsch
  • Patent number: 5891226
    Abstract: Salts of phosphonous acids are useful as flame retardants in plastics. Preferred salts are calcium or aluminum salts of phenylphosphonous acid and of methanephosphonous acid. Plastic molding materials rendered flame-retardant in this way are useful for manufacturing molded parts, especially electrical components, mechanical components, plugs, mounts, housings, coverings, sheathings and overcoatings.
