Visico ME4425/Ambicat™ LE4476 by Borealis A/S is a XLPE (Polyethylene, Crosslinked) plastic material.
General Information
Product Description

Visico ME4425 / Ambicat LE4476 is a silane crosslinkable natural compound designed for low voltage power cables up to 6kV.

The base material Visico ME4425 in combination with the catalyst masterbatch Ambicat LE4476 will accelerate the moisture-induced crosslinking reaction. The system is highly active and crosslinks quickly at ambient conditions, in sauna or in hot water.

When properly mixed, addition of 5 parts of Ambicat LE4476 to 95 parts of Visico ME4425 , insulation with excellent thermo-oxidative stability, also in contact with copper as well as aluminium, is achieved. If the insulation is designed to meet the thermooxidative ageing demand requiring by IEC 60502 at 150°C in contact with copper, addition of 9 parts Ambicat LE4476 to Visico ME4425 is recommended.

Visico ME4425 / Ambicat LE4476 contains antioxidant, metal deactivator and a drying agent. Visico ME4425 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst.

Visico ME4425 / Ambicat LE4476 in combination meets the applicable requirements as below when processed using sound extrusion and testing procedure:
- ASTM D 1248 Type I, Class A, Category 4
- IEC 60502-1
- HD 603 S1
- HD 604 S1
- NEMA WC 70
- NEMA WC 71

The standards referred to above is a selection and is not complete coverage of all applicable standards. Contact your Borealis representative for additional information.

The base material Visico ME4425 in combination with the catalyst masterbatch Ambicat LE4476 is a ready-made two-component system which crosslinks quickly at ambient conditions, in sauna or in hot water. Visico ME4425 is based upon a cost optimised low density polyethylene, copolymerised with vinyl silane. The catalyst/carbon black masterbatch, Ambicat LE4476 , contains a novel, patented, environmentally friendly crosslinking catalyst and is completely free from heavy metals.
