Technical Datasheet | Supplied by Byk (Altana Group)
ADD-VANCE® UVC 623 by Byk (Altana Group) is PP-based, blend of process additives, UV stabilizers, and heat stabilizers. It offers increased efficiency. It protect the polymer during processing at high temperatures by decomposing reactive peroxides. The heat stabilizers act as radical scavengers and inhibit thermo-oxidative degradation in the finished product. The HALS reduces the UV-light induced decomposition of the substrate. It can reduce the viscosity of polymer melt during processing by minimizing friction between the liquid phase and the metal surface of the processing equipment. It possesses high thermal stability in underwater applications and increases stability during heat aging, even after previous water storage at 90°C. ADD-VANCE® UVC 623 provides increased production efficiency. It also prevents adhesion to the metal surfaces of the extruder, the nozzles, and the filter, and ensures a homogeneous finished product. It consists of non-adhesive granulates and is dust-free, safe and easy to handle grade. It is designed for use in geotextiles, PP yarns & fibers and non-woven materials for hydraulic engineering. The dosage level of the grade is 4%.
