| Visico ME4425/Ambicat LE4476是一种硅烷交联天然化合物，专为高达6KV的低压电力电缆设计。基材VISICO ME4425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份添加到95份Visico ME4425中，既可与铜也可与铝接触，具有优异的热氧化稳定性。如果绝缘设计满足IEC 60502在150°C条件下与铜接触时的热氧化老化要求，建议在Visico ME4425上添加9个Ambicat LE4476零件。Visico ME4425/Ambicat LE4476含有抗氧化剂、金属钝化剂和干燥剂。VISICO ME4425含有一种永久性防焦添加剂，确保了安全处理，并能够使用高活性交联催化剂。当使用声音挤压和测试程序进行加工时，Visico ME4425/Ambicat LE4476组合符合以下适用要求：ASTM D 1248 I类，A级，4类，IEC 60502-1 HD 603 S1 HD 604 S1 NEMA WC 70 NEMA WC 71。上述标准是一种选择，并不完全涵盖所有适用标准。联系您的北极星代表以获取更多信息。基础材料Visico ME4425与催化剂母粒Ambicat LE4476结合在一起，是一种现成的双组分系统，可在环境条件下、桑拿或热水中快速交联。Visico ME4425基于成本优化的低密度聚乙烯，与乙烯基硅烷共聚。催化剂/炭黑母粒Ambicat LE4476含有一种新型的专利环保交联催化剂，完全不含重金属。 Visico ME4425 / Ambicat LE4476 is a silane crosslinkable natural compound designed for low voltage power cables up to 6kV. The base material Visico ME4425 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 ME4425 , 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 thermooxidative ageing demand requiring by IEC 60502 at 150°C in contact with copper, addition of 9 parts Ambicat LE4476 to Visico ME4425 is recommended. Visico ME4425 / Ambicat LE4476 contains antioxidant, metal deactivator and a drying agent. Visico ME4425 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst. Visico ME4425 / 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 HD 604 S1 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 ME4425 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 ME4425 is based upon a cost optimised low density polyethylene, copolymerised with vinyl silane. The catalyst/carbon black masterbatch, Ambicat LE4476 , contains a novel, patented, environmentally friendly crosslinking catalyst and is completely free from heavy metals. |
