Borstar® LE8707
LLDPE
博禄/北欧化工(Borealis AG/Borouge)
产品描述
Borstar LE8707 is a black linear low density (LLD) jacketing compound, which is produced with the Borealis proprietary Borstar bimodal process technology.
Borstar LE8707 contains 2.6% well-dispersed carbon black in order to ensure excellent weathering resistance. 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).
Applications
Borstar LE8707 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 LE8707 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of communication and energy cables.
