Visico LE4421/Ambicat LE4472是一种硅烷交联黑色化合物,设计用于架空电缆的覆盖/绝缘。基础材料Visico LE4421与催化剂母粒Ambicat LE4472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 LE4472的7个部分添加到Visico LE4421的93个部分中,可以实现具有优异热氧化稳定性的绝缘,也可以像铝一样与铜接触。最终产品将含有2.25%的优质碳黑,确保良好的耐候性。Visico LE4421/Ambicat LE4472含有抗氧化剂、金属钝化剂和干燥剂。Visico LE4421含有一种永久性防焦添加剂,确保安全处理,并使用高活性交联催化剂。Visico LE4421/Ambicat LE4472组合在使用挤压实践和测试程序进行加工时满足以下适用要求:ANSI/ICEA S-70-547 ASTM D 1248 II类,C级,4类HD 603 S1 HD 626 S1(Tix-2,Tix-4,Tix-6,Tix-9)IEC 60502-1 NEMA WC 71 NEMA WC 70。上述标准是一种选择,并且未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 LE4421与催化剂母粒Ambicat LE4472组合是一种现成的双组分系统,在环境条件下、桑拿或热水中快速交联。Visico LE4421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 LE4472含有一种新型的专利环保交联催化剂,完全不含重金属。 Visico LE4421 / Ambicat LE4472 is a silane crosslinkable black compound designed for covering/insulation of overhead cables. The base material Visico LE4421 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 LE4421 , insulation with excellent thermo-oxidative stability, also in contact with copper as will as aluminium, is achieved. The final product will contain nominal 2,25% of fine size carbon black ensuring excellent weatherability. Visico LE4421 / Ambicat LE4472 contains antioxidant, metal deactivator and a drying agent. Visico LE4421 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst. Visico LE4421 / Ambicat LE4472 in combination meets the applicable requirements as below when processed using extrusion practice 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 71 NEMA WC 70 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 LE4421 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 LE4421 is based upon a cost optimised low density polyethylene, copolymerised with vinyl silane. The catalyst/carbon black masterbatch, Ambicat LE4472 , contains a novel, patented, environmentally friendly crosslinking catalyst and is completely free from heavy metals. |
