Addcross1450 is a silane grafted MDPE 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 1450 is used with Addcross 1334 (a catalyst masterbatch) in the ratio of 95:5. The 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. Addcross1450 is designed for the requirements in ASTM F1281 for hot and cold water pressure multilayer PEX-AL-PEX pipes in inner layer.
