Masterbatch specifications:
Masterbatch is a granular solid with a particle size of 0.1~3mm. 0.1mm (100μm) is powder composed of fine particles; 1~10μm is fine powder; 0.1~1μm is ultrafine powder; >3mm particles are broken solid blocks. The smaller the particle size, the denser the resulting mixture. However, the smaller the particle size of the same solid, the easier it is for the particles to absorb each other and agglomerate. This kind of agglomeration is not easy to open when mixed with another solid particle, and it is difficult to disperse in the plastic melt.
Particle size distribution: The powder with a broad particle size distribution of the masterbatch is denser than that with a narrow particle size distribution. Because the small particle size can enter the gap between the large particles, it is difficult to mix the two powders with large particle sizes.
