Borstar HE6063 is a natural, UV-stabilised, colourable, bimodal 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 HE6063 contains a well dispersed UV-stabiliser in sufficient amount providing a measure of weathering resistance. In order to fully utilise the unique low shink properties of Borstar HE6063 we recommend the use of non-warping colour masterbatches.
The physical toughness and very low water permeability of the compound make it an ideal solution especially for buried power cables. Borstar HE6063 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of communication and energy cables.
Borstar HE6063 meets the applicable requirements as below when processed using sound extrusion practice and testing procedure:
- ASTM D 1248 Type III, Class A, Category 4, Grade E9, J5
- D 620 S1, Part 1, table 4B, DMP 5, 13, 16
- ISO 1872-PE, KHLN, 45 D-006
