FIELD: chemistry.
SUBSTANCE: invention relates to polymer compositions for making cables. Disclosed is a polymer composition for an insulating layer of a cable containing the following in wt.%: (i) low density polyethylene (LDPE) (40–90); (ii) polypropylene homopolymer (5–30); and (iii) a random heterophasic polypropylene copolymer (1.0–15). Invention also discloses a method of producing said composition, a cable containing a layer of said composition, and a method of making said cable, as well as use of the disclosed composition.
EFFECT: use of the disclosed polymer composition enables to obtain a material with high thermomechanical characteristics, such as creep deformation in tension.
