We all know that there is no fixed formula when color masterbatch is matched. The addition of each kind of raw material will have a certain effect on the color. Then, what effect will the product have on the product when titanium dioxide is added:

   (1) Adding titanium dioxide will reduce the transparency of the plastic, and the color will become lighter as the amount of titanium dioxide increases. Therefore, the amount of titanium dioxide must be determined first when the masterbatch is matched. Otherwise, if the amount of titanium dioxide changes, the amount of other pigments will change accordingly.

   (2) Different titanium dioxides have different base colors. For example, the fine particle size titanium dioxide produced by the chloride method has a blue hue, while the coarse particle size titanium dioxide has a yellow hue. This requires special attention when mixing gray.

   (3) Adding titanium dioxide makes the pigment hue change greatly, especially for red varieties after adding titanium dioxide. Yellow light red BBN will turn into a blue tone after adding titanium dioxide, and the more the amount added, the bluer the tone. When titanium dioxide is added to the same particle size of carbon black, carbon black with a small particle size is brownish but yellowish to gray when titanium dioxide is added. Carbon black with a large particle size is blueish but blue to gray when titanium dioxide is added.

   (4) Adding titanium dioxide makes the performance of the pigment greatly changed. Many pigments have poor weather fastness and heat resistance temperature after adding titanium dioxide, such as solid violet RL.

   To sum up, adding titanium dioxide to the masterbatch will not only affect the transparency of the plastic, but the addition of different titanium dioxide will also have a certain effect on the color formed. Therefore, when we match the color of the masterbatch, remember to try a small part of the product first, so as to avoid the inappropriate color and waste of raw materials.
