Visico™ LE4421/Ambicat™ LE4472
The base material Visico LE4421 in combination with the catalyst masterbatch Ambicat LE4472 will accelerate the moisture-induced crosslinking reaction. The system is highly active and crosslinks quickly at ambient conditions, in sauna or in hot water.
When properly mixed, addition of 7 parts of Ambicat LE4472 to 93 parts of Visico LE4421 , insulation with excellent thermo-oxidative stability, also in contact with copper as will as aluminium, is achieved. The final product will contain nominal 2,25% of fine size carbon black ensuring excellent weatherability.
Visico LE4421 / Ambicat LE4472 contains antioxidant, metal deactivator and a drying agent. Visico LE4421 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of highly active crosslinking catalyst.
Visico LE4421 / Ambicat LE4472 in combination meets the applicable requirements as below when processed using extrusion practice and testing procedure:
