PROCESS FOR TREATING POLYAMIDE CHARGED WITH SILICA BY IMPREGNATION IN SUPERCRITICAL CO2

摘要

The present invention relates to a process for treating a material based on polyamide (s) comprising fibers and / or silica fillers, by impregnation with at least one hydrophobic additive in supercritical CO2. It also relates to a material based on polyamide (s) comprising fibers and / or silica fillers and impregnated with at least one hydrophobic additive, obtained by such a process, and to its use as an electrically insulating component in a electrical apparatus, particularly in a circuit breaker.
