Visico LE4423/LE4460/LE4437 LE4423/LE4460/LE4437是一种天然、湿致交联聚乙烯化合物,设计用于低压电线绝缘和护套。VISICO LE4423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。LE4423/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LE4423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,LE4423/LE4460/LE4437表现出良好的氧化热稳定性。LE4423/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色母液,易于着色成各种颜色。通过添加合适的炭黑或紫外线添加剂来获得抗紫外线湿性。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 LE4423/LE4460/LE4437 LE4423/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 LE4423 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. LE4423/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 LE4423 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, LE4423/LE4460/LE4437 exhibits excellent thermal stability to oxidation. LE4423/LE4460/LE4437 is readily pigmented to a variety of colors using standard wire & cable color concentrates designed for thermoplastic or crosslinked polyethylene. UV wether 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. |
