Title (EN) METHOD FOR TREATING A SILICA-FILLED POLYAMIDE BY IMPREGNATING IN SUPERCRITICAL CO2
(FR) PROCEDE DE TRAITEMENT DE POLYAMIDE CHARGE EN SILICE PAR IMPREGNATION DANS LE CO2 SUPERCRITIQUE
Abstract:
(EN) The present invention concerns a method for treating a material made from polyamides(s) comprising silica fibres and/or fillers, by impregnating with at least one hydrophobic additive in supercritical CO2. The invention also relates to a material made of polyamide(s) comprising silica fibres and/or fillers and impregnated by at least one hydrophobic additive, obtained by such a process, and the use of same as an electrically insulating component in an electrical device, in particular in a circuit breaker.
(FR) La présente invention concerne un procédé de traitement d'un matériau à base de polyamide(s) comprenant des fibres et/ou charges de silice, par imprégnation par au moins un additif hydrophobe dans le CO2 supercritique. Elle se rapporte encore à un matériau à base de polyamide(s) comprenant des fibres et/ou charges de silice et imprégné par au moins un additif hydrophobe, obtenu par un tel procédé, et à sa mise en œuvre comme composant électriquement isolant dans un appareil électrique, en particulier dans un disjoncteur.
