| Borstar ME6053 is a natural, UV stabilised, colourable, medium density (MD) 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 ME6053 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 ME6053 we recommend the use of non-warping colour masterbatches. Borstar ME6053 is designed for: Jacket for energy and communication cables Borstar ME6053 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of communication and energy cables. Borstar ME6053 meets the applicable requirements as below when processed using sound extrusion practice and testing procedure: ASTM D 1248 Type II, Class A, Category 4, Grade E8, E9, J4 BS 6234: Type 03, TS2 DIN 57818/VDE 0818 EN 50290-2-24 HD 620 S1, Part 1, table 4B, DMP 5, 13, 16 IEC 60502, Type ST7 IEC 60840, Type ST7 ISO 1872-PE, KHLN, 33 D-006 NF C32-060&& |
