Visico™ LE4423/LE4437

About
Visico LE4423/LE4437 is a scorch retardant, moisture-crosslinking polyethylene compound for low voltage insulation The combination of a VISICO base material, LE4423, and a tin catalyst masterbatch, LE4437, provides a highly scorch retardant compound with excellent thermal stability. LE4423/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. LE4437 should be added to LE4423 directly in the extruder hopper by dry blending a ratio of 5 parts LE4437 to 95 parts LE4423. LE4437 also provides, in addition to catalyst, a stabilizaton package containing suitable antioxidants, a metal passivator and a metal deactivator. Properly mixed, during the extrusion process, LE4423/LE4437 exhibits excellent thermal stability to oxidation. LE4423/LE4437 is readily pigmented to a variety of colors using standard wire & cable concentrates designed for thermoplastic or crosslinked polyethylene. UV weather 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. Specifications Visico LE4423/LE4437 meets the applicable requirements as below when processed using sound extrusion practice and testing procedure: Underwriters Laboratories Standards 854 for types USE and USE-2 EC 502 NBN C 33-321 Canadian Standards Association C22.2 No. 1790-00-Airport Series Lighting Cables and C22.2 No. 38 Cable Type RW-90 NF C33-210 HD 603 S1 NF C32-090 ASTM D 2655 Contact your Borealis representative for additional information.&&
