SULFATE PROCESS · PLASTICS & MASTERBATCH
R-249
Sulfate-process rutile for plastics from high-quality ilmenite. Built for safety-critical, high-temperature applications — masterbatch, films, fiber/spinning — with strong anti-yellowing performance and a good filter pressure value.
R-249 is a rutile titanium dioxide pigment for plastics, produced by the sulfate process from high-quality ilmenite concentrate. A special inorganic and organic coating gives high whiteness with a bluish undertone, high-temperature anti-yellowing performance, and an excellent filter pressure value to support masterbatch productivity.
