Excellent functional masterbatch can lay a foundation for the processing and production of good products. In the process of plastic processing, it is often necessary to add various functional masterbatches to achieve special application effects, such as whitening plastic or making it have certain Special effects such as UV resistance.

The smaller the functional masterbatch particle size, the denser the resulting mixture. However, the smaller the particle size of the same solid, the easier it is to adsorb agglomerates between the particles. This agglomerate is not easily opened when mixed with another solid particle, and is difficult to disperse in the plastic melt. The powder loading with a wide particle size distribution is denser than the narrow particle size distribution.

Powdered particles with too high hardness such as ceramic powder and inorganic antibacterial agent in the functional masterbatch will cause serious wear on the surface of the mixing equipment, which will not only reduce the service life of the equipment, but also make the mixture dark and gray, and when it is serious, it will turn black.
