产品描述
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. - 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 Outdoor - ASTM D 2655 - EC 502 - NF C32-090 - HD 603 S1 - NF C33-210 - Underwriters Laboratories Standards 854 for types USE and USE-2
