Borstar ME6053 is a natural, UV stabilised, colourable, medium density (MD) 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 ME6053 contains a well dispersed UV-stabiliser in sufficient amount providing a measure of weathering resistance.\'20 In order to fully utilise the unique low shink properties of Borstar ME6053 we recommend the use of non-warping colour masterbatches.

Applications
Borstar ME6053 is designed for jacketing of energy and communication cables.
