Visico™ LE4421/LE4432
Visico LE4421/LE4432 is a scorch retardant, moisture-crosslinking polyethylene compound for low voltage insulation
The combination of a VISICO base material, LE4421, and a black 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 L E4421 directly in the extruder hopper by dry blending at a ratio of 10 parts LE4432 to 90 parts LE4421. LE4432 also provides, in addition to catalyst, a stabilization package containing suitable antioxidants, a metal deactivator and a 25% loading of a fine particle size carbon black for UV weather resistance. Properly mixed, during the extrusion process, LE4421/LE4432 exhibits excellent thermal stability to oxidation. The final insulation or jacketing will also contain 2.5% of a suitable carbon black to ensure satisfactory UV weathering stability.
Application
LE4421.LE4432 is recommended for use as insulation for low voltage control cables and power cables up to 6 kv in rating.
Specifications
Visico LE4421/LE4432 can meet a variety of international specifications and standards when produced using sound commercial extrusion practice.
