  • Patent number: 8536449
    Abstract: Insulated wires for use in electronic equipment have an electrically conductive core and an insulating layer and/or a insulating jacket formed of a flame retardant thermoplastic composition surrounding the electrically conductive core. The flame retardant thermoplastic composition includes (A) a thermoplastic copolyester elastomer and/or a copolyamide elastomer as a thermoplastic polymer component, (B) a metal salt of a phosphinic acid and/or a diphosphinic acid and/or a polymer thereof, (C) a nitrogen containing flame retardant synergist and/or a phosphor/nitrogen containing flame retardant as a flame retardant component, and (D) an inorganic compound chosen from basic and amphoteric oxides, hydroxides, carbonates, silicates, borates, stannates, mixed oxide-hydroxides, oxide-hydroxide-carbonates, hydroxide-silicates and hydroxide-borates, and mixtures thereof.

  • Patent number: 6673423
    Abstract: The invention relates to an information-carrying molded part containing one or more plastic layers, at least one of which bears an informative representation. A ‘molded part’ is understood to be in particular a card such as ‘smart cards’, key cards, identification cards, telephone cards, credit cards or bank cards. According to the invention at least one of the plastic layers herein is made from a block-copolyester consisting of soft blocks of a flexible polymer and hard polyester blocks of repeating units of at least one alkylene glycol and at least one aromatic dicarboxylic acid or an ester thereof. The block-copolyether layer can very well be provided with an informative representation with the aid of laser writing and for example sublimation printing. The information-carrying molded part according to the invention also has a good stiffness combined with a good flexibility and a good resistance to breaking and tearing, good adhesion to for example polycarbonate.

  • Patent number: 5914386
    Abstract: The invention relates to a novel copolyester elastomer essentially made up of A: hard polyester segments made up of repeating units derived from an aliphatic diol and an aromatic dicarboxylic acid and B: soft polyester segments made up of repeating units derived from B1: an aliphatic carbonate and, if desired, up to 60% by weight of B, B2: an aliphatic diol and an aliphatic dicarboxylic acid or B3: a lactone, said hard and soft segments being bonded via ester bonds to form copolyesterester units and said copolyesterester units being connected to one another by a urethane group.The novel copolyester elastomer has an exceptionally high thermo-oxidative resistance and resistance to hydrolysis and is used, inter alia, in bellows, seals, pipes, hoses and cable sheathings.
