| Visico LE4423/Ambicat LE4476是一种硅烷交联天然化合物，专为高达6千伏的低压电力电缆设计。基础材料Visico LE4423与催化剂母粒Ambicat LE4476结合将加速水分诱导的交联反应。该系统具有很强的活性，在环境条件下、桑拿或热水中可快速交联。适当混合后，将Ambicat LE4476的5个部分添加到Visico LE4423的95个部分中，既可与铜接触，也可与铝接触，从而实现良好的热氧化稳定性。如果绝缘设计满足IEC 60502在150°C与铜接触的热氧化老化要求，建议在Visico LE4423中增加9部分Ambicat LE4476。Visico LE4423/Ambicat LE4476含有抗氧化剂、金属钝化剂和干燥剂。Visico LE4423含有一种永久性的阻燃添加剂，确保了安全加工并使用高活性的交联催化剂成为可能。Visico LE4423/Ambicat LE4476在使用声音挤压和测试程序进行加工时，其组合满足以下适用要求：ASTM D 1248I类、A类、4类HD 603 S1 HD 604 S1 IEC 60502-1 NEMA WC 70 NEMA WC 71上述标准是选定标准，并不完全覆盖所有适用标准。联系您的北极星代表以获取更多信息。基材Visico LE4423与催化剂母料Ambicat LE4476组合是一种现成的双组分体系，它在环境条件、桑拿或热水中快速交联。Visico LE4423是基于成本优化的低密度聚乙烯，与乙烯基硅烷共聚。该催化剂母料Ambicat LE4476包含一种新型的、专利的、环境友好的交联催化剂，并且完全不含重金属。 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. |
