Yuanjiang Brand titanium dioxide R299 produced by sulfuric acid process is a kind of rutile type titanium dioxide. The zirconia and alumina inorganic surface treatment, with special organic processing agent for surface modification and has a blue phase, easy dispersion, high weatherability, high covering power, low oil absorption, good system compatibility and excellent processing rheological characteristics, is a partial oily, high-quality plastic special titanium dioxide. Can be used for color masterbatch. Using r299 can improve the heat resistance of plastic products and yellowing resistance, improve the mechanical properties of plastic products, at the same time, it can prevent the invasion of UV light and improve the plastic products of light, weather resistance and anti powder properties.

Application characteristics
-
At the end of the blue phase：r299 average particle size is close to the scattering of blue light in titanium dioxide theory the optimum particle diameter, small particle size of TiO2 is higher than that of large particle diameter is more effective, so it has more blue bottom and excellent whiteness.
-
Excellent dispersion：special inorganic surface treatment and organic surface treatment to reduce the contact between the TiO2 particles, so that R299 in the application process showed excellent dispersion. So good wettability, easy to grind.
-
Low oil：R299 low oil, titanium dioxide to maintain good processing performance in the application process in the plastic.
-
High weather resistance：R299 using zirconium coating treatment process to improve the weather resistance and heat resistance of titanium dioxide, and thus the chemical properties are very stable.
-
Good system compatibility：R299 special organic surface treatment, is very suitable for the non polar system and oily system, so in the application showed good system compatibility.
-
Packing：25 kg plastic woven bag for mixed bag or 500, 1000 kg of plastic.
-
Product storage：as long as avoid damp, can be long-term storage.
-
Safety protection：in the treatment of TiO2, should wear gloves and protective cover. If skin contact occurs, the compound will not be dangerous, but it is recommended to clean the skin after use.
