Chlorinated Titanium Dioxide R223 For Polycarbonate
Liangjiang Brand R223 is produced using the chlorination process, using the reference sample R2233 as a comparison. It is designed and manufactured for engineering plastics such as PC, and has strong resistance to polycarbonate degradation caused by the addition of titanium dioxide. It has excellent high-temperature yellowing resistance, is easy to disperse, has a blue background color, high coverage and coloring power, and excellent processing performance. It is mainly used in the field of PC materials (strongly recommended), PC color masterbatch (strongly recommended), PET, PA, ABS and other engineering plastics, It is also recommended to use in plastics that require temperature resistance
Explanation of titanium dioxide for polycarbonate:
Polycarbonate (PC), also known as PC plastic; It is a polymer containing carbonate groups in its molecular chain, which can be classified into various types based on the structure of the ester groups, such as aliphatic, aromatic, and aliphatic aromatic. Due to the lower mechanical properties of aliphatic and aliphatic-aromatic polycarbonates, their application in engineering plastics is limited.
PC is a linear carbonated polyester with alternating carbonate groups and other groups in its molecules, which can be aromatic, aliphatic, or both. Bisphenol A type PC is an important industrial product.
The main performance defects of PC are insufficient hydrolysis stability, sensitivity to notches, resistance to organic chemicals, poor scratch resistance, and yellowing when exposed to ultraviolet light for a long time. Like other resins, PC is susceptible to erosion by certain organic solvents.
PC materials have good acid and oil resistance but are not resistant to alkali, strong acid, amine, or ketone solvents. They are soluble in chlorinated hydrocarbons and aromatic solvents, and long-term immersion in water can easily cause hydrolysis and cracking. Due to the wide application of PC process plastics, titanium dioxide powder is a necessary raw material for plastics. The chlorinated titanium dioxide R-223 titanium dioxide powder is specially designed for the properties of PC polycarbonate materials, which can exhibit strong performance in PC resin and can handle high levels of degradation and fading. Therefore, it is also commonly used in transparent plastics.
Liangjiang Brand R223 is produced using the chlorination process and is designed and manufactured for engineering plastics such as PC, which can replace imported PC titanium dioxide. R223 is a small-sized rutile type titanium dioxide pigment made by post-processing a mixture of aluminum and organic treatment agents. R223 is a blue background color with strong color luster and durability. R223 is a titanium dioxide pigment developed for PC resin, exhibiting matching properties and is capable of molecular weight degradation and fading (yellowing).
The Liangjiang brand R223 is produced using the chlorination process and is designed and manufactured for engineering plastics such as PC. It can replace imported PC titanium dioxide. R223 overcomes the decrease in viscosity and brightness, as well as the increase in the yellowing phase, caused by the degradation of general pigments in the processing of PC and other polymers. R223 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).
