产品描述
Visico LE4423 / Ambicat LE4476 is a silane crosslinkable natural compound designed for low voltage power cables up to 6 kV. The base material Visico LE4423 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 LE4423 , 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 thermo-oxidative ageing demand requiring by IEC 60502 at 150°C in contact with copper, addition of 9 parts Ambicat LE4476 to Visico LE4423 is recommended. Applications Visico LE4423 / Ambicat LE4476 is designed for: - Insulation of low voltage cables for the range up to 6 kV. Additives Visico LE4423 / Ambicat LE4476 contains antioxidant, metal deactivator and a drying agent. Visico LE4423 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of a highly active crosslinking catalyst. Specifications Visico LE4423 / 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 - NEMA WC 70 - HD 604 S1 - 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. Special Features Visico LE4423 / Ambicat LE4476 consists of specially selected components to offer: - Excellent storage stability - Outstanding curing rates - Excellent processing properties - No or little die drool - No volatiles - No drying prior to extrusion - Low scorch - Excellent surface finish - Environmentally friendly (free from heavy metals) The base material Visico LE4423 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 LE4423 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.
