Visico LE4427 / Ambicat LE4476 is a silane crosslinkable natural compound designed for weather resistant covering/insulation of overhead and façade cables.

The black base material Visico LE4427 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 LE4427 , insulation with excellent thermo-oxidative stability, also in contact with copper as well as aluminium, is achieved.

Visico LE4427 / Ambicat LE4476 contains antioxidant, metal deactivator and a drying agent. Visico LE4427 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst.

Visico LE4427 / Ambicat LE4476 in combination meets the applicable requirements as below when processed using sound extrusion and testing procedure:
  • ANSI/ICEA S-70-547
  • ASTM D 1248 Type II, Class C, Category 4
  • HD 603 S1
  • HD 626 S1 (TIX-2, TIX-3, TIX-5, TIX-7, TIX8)
  • NF C33-209 part 6-2 (Except messenger wire)
  • 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 black base material Visico LE4427 in combination with the catalyst masterbatch Ambicat LE4476 is a readymade two-component system which crosslinks quickly at ambient conditions, in sauna or in hot water. The base material Visico LE4427 is a black filled low density polyethylene, copolymerised with vinyl silane and designed for overhead cable covering/insulation. Visico LE4427 contains a well dispersed carbon black to provide the necessary protection for outdoor weatherability according to the French specification NF C 33 209 part 6-2, Cable de Façade. The catalyst masterbatch, Ambicat LE4476 , contains a novel, patented, environmentally friendly crosslinking catalyst and is completely free from heavy metals.
