Addcross1415 is a silane grafted HDPE compound, curable by exposure to moist conditions, circulation of hot water or being at ambient. And shows good extrusion properties at high output rates. Addcross 1415 is used with Addcross1334 (a catalyst masterbatch) in the ratio of 95:5. Highly cross-linked materials produced by the two-component system show excellent impact strength, ESCR, creep and internal pressure resistance under ambient and elevated temperature conditions. Addcross1415 is designed for the requirements in ASTM F1281 for hot and cold water pressure multilayer PEX-AL-PEX pipes in inner layer.
