Chloride Titanium Dioxide R5699 For PC Plastic Modification
The Liangjiang brand R5699 is produced using the chlorination process and is designed and manufactured for engineering plastics such as PC, which can replace imported PC titanium dioxide. R5699 overcomes the decrease in viscosity and brightness, as well as the increase in yellowing phase, caused by the degradation of general pigments in the processing of PC and other polymers. R5699 is a rutile type titanium dioxide pigment that has undergone inorganic and special organic treatment. Its special surface treatment process gives the product excellent anti yellowing performance and anti polyester system degradation ability, high coverage, good dispersibility, and excellent dry powder flowability. It is recommended to use titanium dioxide for polycarbonate (PC).
Main features:
1. Strong resistance to polycarbonate degradation caused by the addition of titanium dioxide
2. Excellent high-temperature resistance to yellowing performance
3. Easy to disperse
4. Blue background color
5. High covering power and high coloring power
6. Excellent processing performance
PC material has good acid and oil resistance, but is not resistant to alkali, strong acid, or amine and ketone solvents. It is soluble in chlorinated hydrocarbons and aromatic solvents. Long-term immersion in water can easily cause hydrolysis and cracking. Because PC engineering plastics are widely used, and titanium white powder is an essential raw material for plastics, the chlorinated titanium dioxide R-5699 titanium white powder is specially formulated for the performance of PC polycarbonate materials, which can show excellent performance in PC resin. It has strong performance and can control molecular degradation and fading, so it is also commonly used in transparent plastics.
