Borstar® LE8706

About
Borstar LE8706 is a natural colourable 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-stabiliser in sufficient amount providing a measure of weathering resistance. Applications Borstar LE8706 is designed for jacketing of 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 as below when processed using sound extrusion practice and testing procedure: ASTM D 1248 Type I, Class A, Category 4, Grade E4, E5, J3 ISO 1872-PE KHLN 23-D012 The following cable material standards are met by Borstar LE8706: EN 50290-2-24 DMP 5, 6, 13, 16, 18 Cables manufactured with Borstar LE8706 using sound extrusion practice normally comply with the following cable product standards: IEC 60840, Type ST7 IEC 60502, Part 2, Type ST7 HD 603 S1, DMP 6 HD 620 S2 Part 1, table 4B, DMP 5, 13, 16, 18 Special Features Borstar LE8706 consists of specially selected components to offer: Superior processability Excellent environmental stress cracking resistance (ESCR) Heat deformation resistance Low coefficient of friction Low water permeability Good petroleum-jelly resistance Very good UV resistance Low shrinkage&&
