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 aluminium, is achieved. Applications Visico LE4423 / Visico LE4438 is designed for: 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 the applicable requirements as below when processed using sound extrusion and testing procedure:
Melt Flow Index (MFI) at 230°C / 2.16 kg, density, polymer melting point and tensile strength. The full Technical Data Sheet (TDS) is available on request.
Suited to injection moulding and forming applications such as rigid containers, caps and engineering parts that demand high stiffness and dimensional stability.
