Now general-purpose plastic special pigments are divided into two forms, one is toner (colored powder), and the other is masterbatch that you speak of. Simple understanding is colored particles, here's the Particles are a kind of carrier, that is, let the color adhere to the carrier, and then use plastic to achieve the purpose of color mixing! Masterbatch is divided into a variety of carriers, PE, PP, EVA which can be used as a carrier for plastic pigments! The advantage of doing so is that the pigment can be evenly distributed in the plastic particles, and the toner is relatively fine, so there will be a low phenomenon and thus lead to color difference! Of course, toner and masterbatch each have their own strengths, and their purpose is to make the plastic better coloring!
