How does the particle size of Masterbatch affect its coloring effect in plastics?
Publish Time: 2024-04-11
The particle size of Masterbatch will directly affect its coloring effect in plastics, mainly in the following aspects:
Uniformity and transparency: Smaller particle size Masterbatch usually disperses better in the plastic matrix, making the color more uniform. In contrast, larger particle size Masterbatch may form particles in the plastic, resulting in uneven coloring or color differences. In addition, a Masterbatch with a smaller particle size can better maintain the transparency of the plastic, while a Masterbatch with a larger particle size may reduce the transparency of the plastic.
Color depth and concentration: Generally, Masterbatch with smaller particle size has better dispersion in plastics, so higher coloring concentration can be achieved, making the plastic appear darker. In comparison, larger particle size Masterbatch may require higher addition amounts to achieve the same coloring effect.
Surface texture: The particle size of Masterbatch will also affect the surface texture of plastic products. Masterbatch with smaller particle sizes usually makes the plastic surface smoother, while Masterbatch with larger particle size may form microscopic bumps on the surface, making the surface feel rougher.
Glossiness: The particle size of Masterbatch will also affect the glossiness of plastic products. Typically, a smaller particle size Masterbatch can make the plastic surface smoother, thereby improving gloss. Masterbatch with a larger particle size may form microscopic bumps on the plastic surface, reducing the gloss.
Therefore, choosing a masterbatch with appropriate particle size is crucial to obtain ideal plastic coloring effects. In practical applications, the appropriate particle size needs to be selected according to specific requirements and needs, and reasonably controlled and adjusted during the production process to ensure that plastic products achieve the expected coloring effect and quality requirements.
