Visico™ LE4421/Ambicat™ LE4476

Generic Family: Polyethylene, CrosslinkedSupplied by: Borealis AG
Visico LE4421 / Ambicat LE4476 is a silane crosslinkable natural compound designed for low voltage power cables up to 6kV.

The base material Visico LE4421 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 LE4421 , 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 LE4421 is recommended.

Visico LE4421 / Ambicat LE4476 contains antioxidant, metal deactivator and a drying agent. Visico LE4421 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst.

Visico LE4421 / Ambicat LE4476 in combination meets the applicable requirements as below when processed using extrusion practice and testing procedure:
  • ASTM D 1248 Type I, Class A, Category 4
  • HD 603 S1
  • HD 604 S1
  • IEC 60502
  • 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 LE4421 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 LE4421 is based upon a cost optimised low density polyethylene, copolymerised with vinyl silane. The catalyst masterbatch, Ambicat LE4476 , contains a novel, patented, environmentally friendly crosslinking catalyst and is completely free from heavy metals.
