Borstar LE8706 is a natural colourable linear low density (LLD) 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 LE8706 contains a well dispersed UV-stabiliser in sufficient amount providing a measure of weathering resistance.

Applications
Borstar LE8706 is designed for jacketing of energy and communication cables.

The abrasion resistance combined with low coefficient of friction makes it ideally suitable for the jacketing of energy and communication cables. Borstar LE8706 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of communication and energy cables.
