Borealis Visico™ LE4421/LE4432 Scorch Retardant, Moisture-Crosslinking Polyethylene Compound for Low Voltage Installation

LE4421/LE4432 is a black, moisture-induced crosslinking polyethylene compound that is designed for use as low voltage wire insulation and jacketing. The combination of a VISICO™ base material, LE4421, and a tin catalyst masterbatch, LE4432, provides a highly scorch retardant compound with excellent thermal stability. LE4421/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. LE4432 should be added to LE4421 directly in the extruder hopper by dry blending at a ratio of 10 parts LE4432 to 90 parts LE4421.LE4421/LE4432 is recommended for use as insulation for low voltage control cables and power cables up to 6 kV in rating.Information provided by the Manufacturer.
