Visico LE4421/LE4460/LE4432 is a scorch retardant, moisture-crosslinking polyethylene compound for low voltage insulation. LE4421/LE4460/LE4432 is a black, halogen-based flame retardant, moisture-induced crosslinking polyethylene compound that is designed for use as low voltage wire insulation and jacketing. The combination of VISICO LE4421 base resin, along with the LE4460 brominated flame retardant masterbatch and the LE4432 tin catalyst masterbatch provides a highly scorch retardant compound with excellent thermal stability and good flame properties. LE4421/LE4460/LE4432 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 70 parts LE4421 mixed with 20 parts of LE4460 and 10 parts of LE4432 is recognized by Underwriters Laboratores as VISICO HORIZONTAL. VISICO HORIZONATAL is designed to reduce normal PE flame spread characteristics and achieve an HB-1 flame rating on 14 AWG wires and larger. LE4432 also provides, in addition to catalyst, a stabilization package containing suitable antioxidants, a metal deactivator and a 25% loading of fine particle size carbon black for UV weather resistance. Properly mixed, during the extrusion process, LE4421/LE4460/LE4432 exhibits excellent thermal stability to oxidation. The final insulation or jacketing will also contain 2.5% of suitable carbon black to ensure satisfactory UV weathering stability. LE4421/LE4460/LE4432 is recommended for use as insulation for low voltage control cables and power cables up to 6 kv in rating.
