Borealis Borstar® HE6062A HDPE
Categories: Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE)

Material Notes: Borstar HE6062A 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 provide excellent physical toughness and environmental stress crack resistance (ESCR). Borstar HE6062A contains well-dispersed carbon black to provide good weathering performance.

Applications: Borstar® HE6062A is intended for following applications: Jackets for energy cables The physical toughness and very low water permeability of the compound make it an ideal solution especially for buried power cables. Borstar HE6062A offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of energy and communication cables.

Typical characteristics:

  • Superior processability
  • Low heat deformation
  • Excellent environmental stress cracking resistance (ESCR)
  • Good UV resistance
  • Excellent abrasion & scratch resistance
  • Low shrinkage
  • Low water permeability
  • Excellent surface hardness
  • Termite resistance
Specifications: Borstar HE6062A is expected to meet the applicable requirements included in the below mentioned standards provided it is processed using sound material handling and processing practices as well as appropriate testing procedures.
