    Appearance color of color masterbatch: The color and color should be fresh and bright, not dull, gray and black

    Masterbatch particles: There are usually two kinds of particles, one is cylindrical and the other is elliptical. In either case, the particles must be uniform, the particle size must be consistent, and the surface should be smooth and free of burrs. Particle particles come from the basic processing technology, drawing and cutting. If the size is different and the surface is rough, it means that the processing technology of the masterbatch itself is very problematic. Do not expect the dispersion of the masterbatch product to have a good performance. .

    Ash content: At present, the price of raw materials is rising, but the product price of the masterbatch itself is constantly decreasing, and the profit space is repeatedly compressed. At this time, we will find a way to reduce costs. Adding mineral powder to the masterbatch is a way. The effect of adding mineral powder on the addition of masterbatch to plastic products is beneficial if it is a small amount, it can increase the rigidity, strength, heat resistance and dimensional shrinkage properties of plastic products. For masterbatch products, mineral powder, usually calcium powder, is added, and the test ash content is generally less than 5%, which has a low impact on product quality, except for special requirements, of course; if the content of added calcium powder is too high, then Not suitable.


Pigment concentration: The higher the pigment concentration, the lower the addition ratio, saving the amount of addition. However, the higher the pigment concentration, the higher the process requirements. For example, if the ordinary machine adds 45% of the pigment concentration, it basically reaches the upper limit, but for a better extruder (import), the amount of pigment added can reach 50% or more. Come out, at the same time the dispersion of the pigment can be done very well.


Coloring power: the same color, the same concentration, the coloring ability of different toners are different, choose masterbatch with strong coloring power can reduce the amount of addition, reduce costs.


Dispersibility: The better the dispersion of the masterbatch, the more uniform the color of the product. It does not look very different for ordinary injection molded products, but for very thin blown film products, the difference is obvious. The masterbatch with good dispersion is made The film products have no obvious defects on the surface; however, the film products prepared by the ordinary color masterbatch have color points, color lines, and holes on the surface. This difference is reflected.

 Okay, let’s stop here. I hope it will help you to choose masterbatch!
