Function refers to a variety of plastic additives masterbatch concentrates, directly adding additives do not disperse readily use efficiency is not high, so often in the form of masterbatch added.
Functional masterbatch particle size: granular solid particle size 0.1 ~ 3mm consisting of powdered solids. Powder 0.1mm (100μm) is composed of fine particles; 1 ~ 10μm as a fine powder; 0.1 ~ 1μm is ultra fine powder; "3mm solid mass of the particles were broken. The smaller the particle size, the more dense the resulting mixture. But the same kind of solid, the smaller the particle size, the more readily adsorbed particles agglomerate with each other, this clumping, mixed with another solid particles when it is not easy to open, in the plastic melt is difficult to spread out.

Functional masterbatch particle size distribution: wide particle size distribution of the powder filling of narrow particle size distribution is more dense than the. Because of the small particle size can enter the large gap between the particles to go, but the big difference between the two kinds of particle size of the powder is mixed, it is difficult fared well.
Masterbatches hardness: the hardness is too high powdery particles - ceramic powder, inorganic antibacterial agent, quartz sand, etc. will cause surface mixing equipment badly worn, not only reduces the life of the equipment, and the mixture is dark in color, gray, serious direct black.
