备注说明 | 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: 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. |
