| Visico™ LE4423 / Visico™ LE4438 is a silane crosslinkable natural compound designed for low voltage power cables up to 6 kV. Visico™ LE4423 and Visico™ LE4438 is a combination of a Visico™ base material and a catalyst master batch which accelerates the moisture-induced crosslinking reaction. When properly mixed, addition of 5 parts of Visico™ LE4438 to 95 parts of Visico™ LE4423, insulation with excellent thermo-oxidative stability, also in contact with copper as well as aluminum, is achieved. Applications: Insulation of low voltage cables for the range up to 6 kV. Additives: Visico™ LE4423 / Visico™ LE4438 contains antioxidant and metal deactivator. Visico™ LE4423 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of a highly active crosslinking catalyst. Specifications: Visico™ LE4423 / Visico™ LE4438 in combination meets these applicable requirements when processed using sound extrusion and testing procedure: ASTM D 1248 Type I, Class A, Category 4; IEC 60502-1; HD 603 S1; HD 604 S1; NEMA WC 70; and NEMA WC 71.Information provided by Borealis AG |
