CHLORIDE PROCESS - PLASTICS & MASTERBATCH
CR-340
Chloride-process rutile for plastics. Tight particle-size control and surface treatment built for high-concentration masterbatch, high-quality films, and 300°C heat resistance against yellowing.
CR-340 is a rutile titanium dioxide pigment for plastics produced by the chloride process. Advanced particle-size control and surface treatment deliver the dispersibility needed to improve masterbatch productivity, high whiteness with a bluish undertone, and 300 °C heat resistance to protect against yellowing.
