Abstract
This invention relates to a treatment process for a material chosen from among a polyamide, a polyester and a poly(meth)acrylate. According to the invention, this process comprises a step in which contact is made between this material and a polar organic solvent in a supercritical fluid. This invention also relates to a process for manufacturing a part from a material chosen from among a polyamide, a polyester and a poly(meth)acrylate in a divided form. Finally, the invention relates to use of the material treated by the treatment process and to use of the part manufactured by the manufacturing process in the low voltage, medium voltage or high voltage electrical industry.
