Borealis Borstar® HE 6068 Natural Bimodal HDPE with very low shrinkage for Submarine and Fiber Optical Cables

Borstar® HE6068 is a natural, UV-stabilized, colorable, 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-stabilizer 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 applicable requirements as below when processed using sound extrusion practice and testing procedure: ASTM D 1248 Type III, Class A, Category 3, Grade E8, E9, J4, BS 6234: Type H2, TS2, DIN 57818/VDE 0818, HD 620 S1, Part 1, table 4B, DMP 5, 13, 16, IEC 60502, Type ST7, IEC 60840, Type ST7, and ISO 1872-PE, KHLN, 45 D-022.Information provided by Borealis AG
