Borealis Borstar® LE8706 Natural Bimodal LLDPE Jacketing Compound for Energy and Communication Cables
Categories: Polymer; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE)
Material Notes: Borstar® LE8706 is a natural colorable linear low density (LLD) 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® LE8706 contains a well dispersed UV-stabilizer in sufficient amount providing a measure of weathering resistance. Applications: jacket for energy and communication cables. The abrasion resistance combined with low coefficient of friction makes it ideally suitable for the jacketing of energy and communication cables. Borstar® LE8706 offers a balance of properties giving advantages in manufacturing, installation and lifetime performance of communication and energy cables. Specifications: Borstar® LE8706 meets the applicable requirements when processed using sound extrusion practice and testing procedure: ASTM D 1248 Type I, Class A, Category 4, Grade E4, E5, J3; BS 6234: Type 03, TS2; EN 50290-2-24; IEC 60502, Type ST7; IEC 60840, Type ST7; HD 603 S1, Part 1, table 4B, DMP 6; HD 620 S1, Part 1, table 4B, DMP 5, 16
