Visico™ ME4425/LE4462 is a silane crosslinkable black compound system designed for overhead track resistant energy cables. Visico™ ME4425 is a medium density polyethylene, copolymerized with vinyl silane. Visico™ LE4462 is a crosslinking catalyst masterbatch specially designed to be used with Visico ME4425 to accelerate the moisture-induced reaction and impact track resistance. The system crosslinks quickly in sauna or in hot water. Cable insulation with a proper mixture of Visico ME4425 (90 parts) and Visico LE4462 (10 parts) exhibits excellent thermo-oxidative stability. The system can be used with aluminum for overhead cables and covered conductors. The use of ME4425 and LE4462 is designed to provide good weathering performance. If a semiconductive inner layer is required, we recommend to use Borealis LE0542 together with Visico ME4425/LE4462.
