Material Notes:
Visico LE4423 is a natural, ethylene vinyl silane copolymer that, when combined with the catalyst masterbatch Ambicat LE4476, will undergo an accelerated, moisture-induced crosslinking reaction. This polyethylene compound is highly active and crosslinks rapidly under ambient temperature and humidity conditions, as well as, in a sauna or hot water bath. The combinations of the Visico medium-density polyethylene base material, ME4425, and the patented sulphonic acid catalyst masterbatch, LE4476, provides a highly scorch retardant compound with excellent thermal stability. The higher density of ME4425 exhibits greater chemical resistance, toughness and improved heat deformation resistance. ME4425 contains a permanent scorch retardant additive (SRA) that increases the processing window for moisture crosslinking compound, minimizes the tendency for premature crosslinking in the extruder, head or die and allows the use of highly active crosslinking catalyst like LE4476. LE4476 should be added to ME4425 directly in the extruder hopper by dry blending at a ratio of 5 parts LE4476 to 95 parts ME4425.Information provided by the Manufacturer.
