Visico ME4425 / Ambicat LE4472 is a silane crosslinkable black compound designed for covering/insulation of overhead cables. The base material Visico ME4425 in combination with the catalyst masterbatch Ambicat LE4472 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 7 parts of Ambicat LE4472 to 93 parts of Visico ME4425 , insulation with excellent thermo-oxidative stability, also in contact with copper as will as aluminium, is achieved. The final product will contain nominal 2,5% of fine size carbon black ensuring excellent weatherability. Visico ME4425 / Ambicat LE4472 contains antioxidant, metal deactivator and a drying agent. Visico ME4425 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst. Visico ME4425 / Ambicat LE4472 in combination meets the applicable requirements as below when processed using sound extrusion and testing procedure: ANSI/ICEA S-70-547 ASTM D 1248 Type II, Class C, Category 4 HD 626 S1 (TIX-2, TIX-4, TIX-6, TIX-9) HD 603 S1 NEMA WC 70 NEMA WC 71 IEC 60502-1 The standards referred to above is a selection and is not complete coverage of all applicable standards.Contact your Borealis representative for additional information.
