METHOD OF SECONDARY TREATMENT OF LOW-DENSITY POLYETHYLENE FILM AFTER ATMOSPHERIC AGEING

摘要

The invention relates to the technology of processing thermoplastics and can be used in the regeneration of polyethylene from waste film that has been in operation. The invention makes it possible to increase the melt index of recycled polyethylene by a factor of 2.5, to reduce the dielectric loss tangent by a factor of 4 while maintaining the mechanical properties by carrying out additional extrusion after crushing, crushing and drying the film in a disk This shear rate 300 - 900, 1 tab. with (L
