Title (EN) FLAME RETARDANT POLYMER COMPOSITIONS COMPRISING STABILIZED HYPOPHOSPHITE SALTS
(FR) COMPOSITIONS POLYMÈRES IGNIFUGES COMPRENANT DES SELS D'HYPOPHOSPHITE STABILISÉS
Abstract: front page image
(EN)The current invention discloses a flame retardant polymer composition comprising at least one polymer and a hypophosphite salt, wherein: -the hypophosphite salt is so heat stabilized that, when it is heated during 3 hours at 298 ℃ under a flow of argon flushing at rate 58 mL/mins, it generates less than 0.5 mL of phosphine per gram of hypophosphite salt; -the flame retardant polymer composition further comprises at least an additive improving the flame retardant properties of the composition.
(FR)L'invention concerne une composition polymère ignifuge comprenant au moins un polymère et un sel d'hypophosphite. Le sel d'hypophosphite est stabilisé à la chaleur de sorte que, lorsqu'il est chauffé pendant 3 heures à 298 °C sous un flux d'argon s'évacuant à une vitesse de 58 mL/min, il génère moins de 0,5 mL de phosphine par gramme de sel d'hypophosphite; la composition polymère ignifuge comprend également au moins un additif améliorant ses propriétés ignifuges.
