Material Notes:
Visico LE4423 is a natural, ethylene vinyl silane copolymer that, when combined with the catalyst masterbatch Ambicat LE4472, 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 base material, LE 4423, and the patented sulphonic acid catalyst masterbatch, LE4476, provides a highly scorch retardant compound with excellent thermal stability. LE4423 contains a permanent scorch retardant additive (SRA) that increases the processing window for a moisture crosslinking compound, minimizes the tendency for premature crosslinking in the extruder, head or die and allows the use of a highly active crosslinking catalyst like LE4476. LE4476 should be added to LE4423 directly in the extruder hopper by dry blending at a ratio of 5 parts LE4476 to 95 parts LE4423. Information provided by the Manufacturer.
