Abstract:
A process for the recycling of a cross-linked thermoplastic polythenes polymeric material coming from machining scraps of electric cable coating materials, characterized in that it comprises a mechanical mixing cycle of said cross-linked thermoplastic polythenes polymeric material carried out in an extruder-mixer having a feed zone, at least one mixing zone and an extrusion head, during which said cross-linked thermoplastic polythenes polymeric material is submitted for a pre-established time to a mechanical mixing action and to shear stresses higher than a pre-established value in the range of 50 to 150 S.sup.-1, and wherein the extruder-mixer is heated so as to have an increasing temperature profile from its feed zone to its extrusion head, such as to cause dereticulation of said material.
