Visico™ LE4423/Ambicat™ LE4472

Visico LE4423 / Ambicat LE4472 is a silane crosslinkable black compound designed for covering/insulation of overhead cables.

The base material Visico LE4423 in combination with the catalyst masterbatch Ambicat LE4472 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 7 parts of Ambicat LE4472 to 93 parts of Visico LE4423 , insulation with excellent thermo-oxidative stability, also in contact with copper as will as aluminium, is achieved. The final product will contain nominal 2,5% of fine size carbon black ensuring excellent weatherability.

Visico LE4423 / Ambicat LE4472 contains antioxidant, metal deactivator and a drying agent. Visico LE4423 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst.

Visico LE4423 / Ambicat LE4472 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-4, TIX-6, TIX-9)

• IEC 60502-1

• 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 LE4423 in combination with the catalyst masterbatch Ambicat LE4472 is a ready-made two-component system which crosslinks quickly at ambient conditions, in sauna or in hot water. Visico LE4423 is based upon a cost optimised low density polyethylene, copolymerised with vinyl silane.
