Important Notes
General-purpose (TITAN-type) cannot be used for cosmetic, food-contact or pharmaceutical applications due to impurity limits.
Oil absorption is a key indicator: lower oil absorption improves loading capacity in plastics & inks.
Heavy-metal specifications are much stricter for cosmetic grade.
High-weather-resistant grade adopts thicker inorganic coating to reduce photo‑catalytic activity.
Available grades
Coating grade, Plastic grade, Cosmetic grade, Food-contact grade, pharmaceutical grade etc. Surface-treated (Al/Zr coated) and untreated types are optional.
