CA 2401785
The invention relates to flame-resistant polycarbonate compositions which are made flame-resistant without the use of chlorine or bromine. Said compositions contain <= 0.1 wt. % fluorine and are characterised by excellent flame resistance, even with low wall thickness, combined with improved mechanical, thermal and rheological properties and especially by good ESC properties. The invention also relates to the use of the inventive polycarbonate moulding compounds for producing moulded bodies and moulded parts and all kinds of extrusion profiles.
L'invention concerne des compositions ignifuges à base de polycarbonate, ignifugées sans chlore et sans plomb, qui contiennent <= 0,1 % en poids de fluor et se caractérisent par un excellent pouvoir ignifugeant, y compris en cas de parois étroites, associé à des propriétés mécaniques, thermiques et rhéologiques améliorées et notamment par un bon comportement en fissuration sous contrainte environnementale. L'invention concerne en outre l'utilisation des matières de moulage à base de polycarbonate selon l'invention pour produire des corps moulés et des pièces moulées, ainsi que des profilés d'extrusion de tout type.
