FIELD: polymer production.
SUBSTANCE: expendable composition of a polymer compound for the manufacture of a cable sheath layer and a cable containing a sheath layer that contains an expendable composition obtained from an expendable polymer composition, while the expendable polymer composition contains: (A) a polyolefin polymer and (B) an expendable agent in an amount of from 0.01 to 3% by weight relative to the total weight of the expendable polymer compound, where the expendable agent consists of expanding polymer microspheres, where the specified composition does not contain a fluorinated resin. While the polyolefin polymer (A) does not contain silane fragments and contains from at least 20 to 99.99% by weight of linear low-density polyethylene.
EFFECT: providing a cable with a sheath layer of improved flexibility, which is indicated by a lower value of the flexural modulus, while the breaking tensile stress and elongation at break remain acceptable.
