Non-woven masterbatch, masterbatch manufacturers to tell you that the black non-woven masterbatch is the use of carbon black to produce, and today let us follow the Hangzhou Yujie Chemical Co., Ltd. to explore the next, decided to black non-woven masterbatch quality Factors, specifically the following aspects:
1, rheological: If a masterbatch itself has a good dispersion, but it can not flow into the material to be molded, the production effect is not ideal. In general, the backing resin used to produce the masterbatch has a high rheology. In order to save costs, some masterbatch producers use reusable materials, scrap or recycled materials as resin carriers;
2, the degree of dispersion: raw carbon black is very difficult to handle and dirty mixture, it is covered with dust, light weight, was fluffy. Unless it takes a large-scale treatment, it will dirty machines and workers, so that the working environment becomes dirty
3. Coverage: This factor is particularly important for masterbatches for waste or recycled polymers. In these cases, the black effect is to cover other colors in the waste. Large particles of carbon black coloring ability is poor, not easy to cover all the other in the lower color, the results of the final product only get away from the color. In the process of melting, the ability to correctly select the carbon black with high coloring ability to cover the existing color is the so-called covering force;
4, compatibility: If the masterbatch is produced using chips or recycled materials, then it may contain contaminants or other non-meltable polymer. This can cause some unpredictable, difficult to restrain the trouble, wasting the time and raw materials of the final consumer. At this time, you can use the backing resin to produce high-quality masterbatch, masterbatch in the melting process have a good compatibility. High quality masterbatch can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials;
