Material Notes:
Visico LE4421 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 combination of the Visico base material, LE4421, and the patented sulphonic acid catalyst masterbatch, LE4472, provides a highly scorch retardant additive (SRA) that increases with excellent thermal stability. LE 4421 contains a permanent scorch retardant additive (SRA) that increases the processing window for a moisture crosslinking compound, minimized the tendency for premature crosslinking in the extruder, head or die and allows the use of a highly active crosslinking catalyst like LE4472. LE4472 should be added to LE4421 directly in the extruder hopper by dry blending at a ratio of 7 parts LE4472 to 93 parts LE4471.Information provided by the Manufacturer.
