Masterbatch is a colorant widely used in the fields of plastic products, rubber products, fiber products, etc. There are certain differences in the performance of Masterbatch of different colors.
First of all, in terms of color stability, Masterbatch of different colors performs differently. Some dark-colored Masterbatch, such as black, dark blue, etc., usually have good light resistance and heat resistance, and the color is not easy to fade or change. This is because the molecular structure of dark-colored pigments is relatively stable and can better resist the influence of external environmental factors. On the other hand, light-colored Masterbatch, such as white, light yellow, etc., has relatively poor color stability and is easily affected by ultraviolet rays, high temperature and other factors and turns yellow or fades.
Secondly, Masterbatch of different colors also differs in hiding power. Generally speaking, dark-colored Masterbatch has strong hiding power and can effectively cover the base color of plastic products, making the products present a uniform color. On the other hand, light-colored Masterbatch has weak hiding power and requires a higher addition ratio to achieve a better coloring effect. In addition, some special colors of Masterbatch, such as metallic and fluorescent colors, also have their own unique characteristics in hiding power. Metallic Masterbatch usually has a strong metallic luster, but the hiding power is relatively weak; fluorescent Masterbatch will emit strong fluorescence under certain lighting conditions, but the hiding power is also relatively limited.
Furthermore, Masterbatch of different colors also differ in dispersibility. Good dispersibility enables Masterbatch to be evenly dispersed in plastic products to avoid problems such as color spots and color dots. Generally speaking, dark-colored Masterbatch has relatively poor dispersibility due to its large pigment particles, and some dispersants are needed to improve its dispersibility. Light-colored Masterbatch has smaller pigment particles and relatively better dispersibility.
In addition, Masterbatch of different colors also differ in chemical resistance. Some colors of Masterbatch may have better tolerance to specific chemicals, but are prone to discoloration or fading to other chemicals. For example, red Masterbatch may have better tolerance to acidic substances, but is prone to discoloration to alkaline substances.
In short, Masterbatches of different colors have certain differences in performance. When selecting Masterbatch, it is necessary to comprehensively consider factors such as color stability, hiding power, dispersibility, chemical resistance, etc. according to specific application needs and product requirements, and select the appropriate Masterbatch to ensure the quality and appearance of plastic products.
