Applications Visico LE4421M / Visico LE4431M is intended for insulation of XLPE medium voltage cables with rated voltages up to 36 kV. Specifications Visico LE4421M / Visico LE4431M in combination meets the applicable requirements as below when processed using sound extrusion and testing procedure: IEC 60502-2 Cenelec HD620 S2 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 LE4421M / Visico LE4431M is a ready-to-use two part system. It provides the following advantages: Quick change-over for short length cables Long shelf life Longer production runs between cleaning stops Low odour during processing Very good surface finish	Visico LE4421/LE4460/LE4437是一种用于低压绝缘的防焦、湿交联聚乙烯化合物LE4421/LE4460/LE4437是一种天然、湿交联聚乙烯化合物，设计用于低压电线绝缘和护套。VISICO LE4421基树脂与LE4460溴化阻燃母粒和LE4437催化剂的结合，提供了一种具有优异热稳定性和良好阻燃性能的高烧焦阻燃化合物。LE4421/LE4460/LE4437含有一种获得专利的防焦添加剂（SRA），该添加剂增加了湿交联化合物的加工窗口，并将挤出机、机头或模具中过早交联的趋势降至最低。由75份LE4421与20份LE4460和5份LE4437混合而成的成品化合物被保险商实验室认定为Visico Horizontal。Visico Horizontal旨在降低普通PE火焰蔓延特性，并在14 AWG及以上电线上实现HB-1火焰等级。除催化剂外，LE4437还提供含有适当抗氧化剂、金属钝化剂和金属钝化剂的稳定包。适当混合，在挤出过程中，LE4421/LE4460/LE4437表现出良好的氧化热稳定性。LE4421/LE4460/LE4437使用为热塑性聚乙烯或交联聚乙烯设计的标准电线和电缆颜色浓缩物容易着色成各种颜色。通过添加适当的炭黑或紫外线添加剂，可获得抗紫外线天气性能。使用Visico LE4432代替LE4437将锡催化剂与适当的炭黑结合在一起，以提供黑色、抗紫外线、防潮交联电缆绝缘。 Visico LE4421/LE4460/LE4437 is a scorch retardant, moisture-crosslinking polyethylene compound for low voltage insulation LE4421/LE4460/LE4437 is a natural, moisture-induced crosslinking polyethylene compound that is designed for use as low voltage wire insulation and jacketing. The combination of a VISICO LE4421 base resin, along with the LE4460 brominated flame retardant masterbatch and the LE4437 catalyst, provides a highly scorch retardant compound with excellent thermal stability and good retardant flame properties. LE4421/LE4460/LE4437 contains a patented scorch retardant additive (SRA) that increases the processing window for a moisture crosslinking compound and minimizes the tendency for premature crosslinking in the extruder, head or die. A finished compound that is composed of 75 parts of LE4421 mixed with 20 parts of LE4460 and 5 parts of LE4437 is recognized by Underwriters Laboratories as VISICO HORIZONTAL. VISICO HORIZONTAL is designed to reduce normal PE flame spread characteristics and achieve an HB-1 flame rating on 14 AWG wires and larger. LE4437 also provides, in addition to catalyst, a stabilization package containing suitable antioxidants, a metal passivator and a metal deactivator. Properly mixed, during the extrusion process, LE4421/LE4460/LE4437 exhibits excellent thermal stability to oxidation. LE4421/LE4460/LE4437 is readily pigmented to a variety of colors using standard wire & cable color concentrates designed for thermoplastic or crosslinked polyethylene. UV weather resistance is obtained by the addition of a suitable carbon black or UV additive. Using Visico LE4432 in place of LE4437 combines a tin catalyst along with the proper carbon black to provide a black, UV resistant, moisture crosslinking cable insulation.
