Disclosed is a polymer composition having a semi-homogeneous phase that exhibits excellent electrical, mechanical and thermal properties while satisfying flexibility, bendability and impact resistance. More specifically, disclosed is a polymer composition having a morphology in which a rubber-phase filler of a propylene copolymer is dispersed in a matrix of polypropylene, wherein an elution rate of the rubber-phase filler in a xylene-based solvent is less than 50%, based on the content of the rubber-phase filler such that the rubber-phase filler forms a semi-homogeneous phase with the matrix.

Polymer composition based on polypropylene/propylene copolymer having semi-homogeneous phase

Disclosed is an eco-friendly polymer composition for an insulation layer of power cables having a morphology in which a second phase substance of polypropylene composite is dispersed in a first phase substance of polypropylene, wherein the polypropylene composite of the second phase substance has a morphology in which an at least partially cured elastomer is dispersed as a filler in a matrix of polypropylene.

Polymer composition for insulation layer of power cable, insulation layer including the same and power cable including the same

Disclosed is a heterophasic polymer composition for environmentally friendly cable insulation layers that exhibits excellent electrical, mechanical, and thermal properties while realizing the flexibility, bendability, and impact resistance performance characteristics of polypropylene. The heterophasic polymer composition for cable insulation layers is configured such that propylene copolymer particles each having a predetermined size are dispersed in a polypropylene matrix.
