Visico™LE4423 / /Ambicat™LE4476

Visico™ LE4423 / Ambicat™ LE4476 is a silane crosslinkable natural compound system designed for insulation of low voltage energy cables. Visico LE4423 is a low density polyethylene, copolymerised with vinyl silane. Ambicat LE4476 is an ambient crosslinking catalyst masterbatch specially designed to be used with Visico base resins. The system is highly active and crosslinks quickly at ambient conditions, in sauna or in hot water. Cable insulation with a proper mixture of Visico LE4423 (95 parts) and Ambicat LE4476 (5 parts) exhibits excellent thermo-oxidative stability. The combination is suitable for both copper and aluminum conductors. If the insulation is designed to meet the thermo-oxidative ageing demand required by IEC 60502 at 150°C in contact with copper, the addition of 9 parts Ambicat LE4476 to Visico LE4423 is recommended.
