Borstar ME6052 is a black bimodal polyethylene 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 ME6052 contains 2.5% well-dispersed carbon black in order to ensure excellent weathering resistance.
