FIELD: chemistry.
SUBSTANCE: invention relates to technological processes of recycling polymer materials. Disclosed is a peroxide-crosslinked composition for making cable insulation, containing organic peroxide, colloidal silicon dioxide, an electrochemical aging stabilizer, medium and high viscosity polydimethylsiloxanes, antioxidants, copolymer of polyolefin and low-density polyethylene, where the electrochemical aging stabilizer used is pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), and the low-density polyethylene used is secondary low-density polyethylene.
EFFECT: obtaining an effective polymer composition during processing of secondary raw materials for coating cables, which enables to increase their service life.
