Borstar® HE6068

About
Borstar HE6068 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 HE6068 contains a well dispersed UV-stabiliser in sufficient amount providing a measure of weathering resistance. Applications Borstar HE6068 is designed for: Submarine and fibre optical cables Borstar HE6068 offers substantially reduced shrinkage which helps to maintain low signal attenuation for fibre optic communication cables and low jacket retraction for energy cables in combination with excellent mechanical and barrier properties. Borstar HE6068 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of communication and energy cables. Specifications Borstar HE6068 meets the following material classification: ISO 1872-PE, KHLN, 45 D-022 ASTM D 1248 Type III, Class A, Category 3, Grade E8, E9, J4 The following cable material standards are met by Borstar HE6068: DMP 5, 7, 13, 16, 18 EN 50290-2-24 Cables manufactured with Borstar HE6068 using sound extrusion practice normally comply with the following cable product standards: IEC 60502, Part 2, Type ST7 IEC 60840, Type ST7 HD 603 S1, DMP 6 DIN VDE 0818 HD 620 S2, Part 1, table 4B, DMP 5, 13, 16, 18 Special Features Borstar HE6068 consists of specially selected components to offer: Superior processability Excellent environmental stress cracking resistance (ESCR) Excellent abrasion & scratch resistance Low water permeability Good petroleum-jelly resistance Termite resistance Very good UV resistance Very low shrinkage Excellent surface hardness&&
