Abstract[English]
A polycarbonate composition suitable for thin-wall applications comprises: a polycarbonate; a polycarbonate comprising repeating units derived from a monomer comprising a pendant ester group; a non-halogenated flame retardant, optionally, a poly(carbonate-siloxane) present in an amount effective to provide 4 wt% or less of siloxane repeating units, based on the total weight of the composition, and optionally, an additive composition wherein a sample of the composition has a UL-94 flame test rating of V-0 at a thickness of 1.5 mm or thinner. Advantageously, the polycarbonate compositions may minimize or eliminate fluorinated flame retardant salts such as Rimar salt and fluorinated anti-drip agents while achieving improved flame test performance.[French]
L'invention concerne une composition de polycarbonate appropriée pour des applications à paroi mince comprenant : un polycarbonate; un polycarbonate comprenant des unités de répétition dérivées d'un monomère comprenant un groupe ester pendant; un retardateur de flamme non halogéné, éventuellement, un poly (carbonate-siloxane) présent en une quantité efficace pour fournir 4% en poids ou moins d'unités de répétition de siloxane, sur la base du poids total de la composition, et éventuellement, une composition d'additif dans laquelle un échantillon de la composition a une note de test de flamme UL-94 de V-0 à une épaisseur de 1,5 mm ou plus mince. De manière avantageuse, les compositions de polycarbonate peuvent réduire au minimum ou éliminer des sels ignifuges fluorés tels que le sel de Rimar et des agents anti-goutte fluorés tout en obtenant une performance de test de flamme améliorée.
