Visico LE4421 / Visico LE4438 is a silane crosslinkable natural compound designed for low voltage power cables up to 6 kV. Visico LE4421 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 LE4421 , insulation with excellent thermo-oxidative stability, also in contact with copper as well as aluminium, is achieved. |
