Borstar HE6067 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 with excellent physical toughness and environmental stress crack resistance (ESCR) properties.

Borstar HE6067 contains 2.5% well-dispersed carbon black in order to ensure excellent weathering resistance.

Borstar HE6067 offers substantially reduced shrinkage which helps to maintain low signal attenuation for fibre optic communication cables and low jacket retraction for energy cables in combination with excellent mechanical and barrier properties. Borstar HE6067 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of communication and energy cables.
