Abstract
Disclosed are polymeric compositions suitable for use as cable jackets. The polymeric compositions include a polymer component and, optionally, one or more additives. The polymer component consists of an ethylene-based polymer and an olefin block copolymer. The polymer component has a tensile elasticity (G′) of less than 1,200 MPa when measured at −40° C., a tensile elasticity (G′) below 400 MPa when measured at 20° C., a tensile strength greater than 1,000 psi, and an elongation at break greater than 800%.

A cable comprising:
- (a) a conductor;
- and
- (b) an outer jacket,
- wherein the outer jacket is at least partially formed from a polymeric composition,
- wherein the polymeric composition comprises a polymer component and optionally one or more additives,
- wherein the polymer component consists of:
- (i) an ethylene-based polymer selected from a low-density polyethylene, a linear-low-density polyethylene, or combinations thereof, and
- (ii) an olefin block copolymer,
- wherein the polymer component has a tensile elasticity (G′) of less than 1,200 MPa when measured at −40° C.,
- wherein the polymer component has a tensile elasticity (G′) of less than 400 MPa when measured at 20° C.,
- wherein the polymer component has a tensile strength greater than 1,000 psi,
