ADD-VANCE® NU 489 (formerly:ADD-VANCE ® 489)

ADD-VANCE® NU 489 (formerly:ADD-VANCE ® 489) by AddComp (Altana Group) is a PP based high performance nucleation masterbatch. It outperforms traditional agents such as talc, benzoate salts and phosphate-ester salts. It is formulated to increase both crystallization rate and number of spherulites in a polymer. The faster crystallization allows greater productivity in molding as well as extrusion processes and increased number of spherulites helps to improve stiffness as well as heat deflection temperature. Exhibits improved product isotropy which results in more controlled shrinkage and less warpage. It also offers an improvement in flexural modulus but Gardner and Izod impact remain comparable. It eliminates surface defects as well as voids and provides pigment nucleation levelling. Used in extruded and injection molded articles made from PP resins. ADD-VANCE® NU 489 (formerly:ADD-VANCE ® 489) can also be used in blow molded and injection molded articles such as closures, packaging and automotive parts. Recommended dosage level is 2.5-5 wt%.
