Borealis Visico™ LE4421/LE4460/LE4432 Scorch Retardant, Moisture-Crosslinking Polyethylene Compound for Low Voltage Installation

 

Subcategory: Polyethylene; Thermoplastic; LDPE

Material Notes:
Visico 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 the 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 that 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 Laboratories as Visico Horizontal.

LE4421/LE4460/LE4432 is recommended for use as insulation for low voltage control cables and power cables up to 6 kV in rating.
