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:
مؤشر التدفق الانصهاري (MFI) عند 230°م / 2.16 كجم، الكثافة، درجة انصهار البلمرة ومقاومة الشد. تتوفر ورقة البيانات الفنية الكاملة (TDS) عند الطلب.
مناسب لتطبيقات الحقن البلاستيكي والتشكيل، مثل الحاويات الصلبة والأغطية والقطع الهندسية التي تتطلب صلابة عالية وثبات الأبعاد.
