Borstar HE6062 is a black high density (HD) jacketing compound, which is produced with the Borealis proprietary
Borstar bimodal process technology.

Borstar technology allows the manufacturing of polymers outside the traditional MFR and density range making it possible to optimize processability, reduce shrinkage and yet provide excellent physical toughness and environmental stress crack resistance (ESCR).

Borstar HE6062 contains 2.5% well-dispersed carbon black in order to ensure excellent weathering resistance.

Applications
Borstar HE6062 is designed for jacketing of energy and communication cables.

The physical toughness and very low water permeability of the compound make it an ideal solution especially for buried power cables. Borstar HE6062 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of energy and communication cables.
