Visico ME4425 / Visico LE4438 is a silane crosslinkable natural compound system designed for insulation of low voltage energy cables. Visico ME4425 is a medium density polyethylene, copolymerized with vinyl silane. Visico LE4438 is a crosslinking catalyst masterbatch specially designed to be used with Visico base resins. The system crosslinks quickly in sauna or in hot water. Cable insulation with a proper mixture of Visico ME4425 (95 parts) and Visico LE4438 (5 parts) exhibits excellent thermo-oxidative stability. The combination is suitable for both copper and aluminium conductors. Applications Visico ME4425 / Visico LE4438 is designed for: Insulation of low voltage energy cables, range up to 6 kV Specifications Visico ME4425 / 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.
