Material Notes:
Visico™ LE4427 / Ambicat™ LE4476 is a silane crosslinkable black compound designed for weather resistant covering/insulation of overhead and façade cables. The black base material Visico™ LE4427 in combination with the catalyst masterbatch Ambicat™ LE4476 will accelerate the moisture-induced crosslinking reaction. The system is highly active and crosslinks quickly at ambient conditions, in sauna or in hot water. When properly mixed, addition of 5 parts of Ambicat™ LE4476 to 95 parts of Visico™ LE4427 , insulation with excellent thermo-oxidative stability, also in contact with copper as well as aluminum, is achieved. Applications: Weather resistant covering/insulation of overhead and façade cables. Additives: Visico™ LE4427 / Ambicat™ LE4476 contains antioxidant, metal deactivator and a drying agent. Visico™ LE4427 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of a highly active crosslinking catalyst. Specifications: ANSI/ICEA S-70-547; ASTM D 1248 Type II, Class C, Category 4; HD 603 S1; HD 626 S1 (TIX-1, TIX-3, TIX-5, TIX-7, TIX8); NF C33-209 part 6-2 (Except messenger wire); NEMA WC 70; and NEMA WC 71.Information provided by Borealis AG
