What are the commonly used classification methods for black masterbatches

1: Masterbatch coloring has the following advantages compared with granulation coloring: 9.1. Coloring and product processing are completed at one time, avoiding the heating process of granulation and coloring on plastics, which is good for protecting the quality of plastic products. 9.2. Simplify the production process of plastic products. 9.3. Can save a lot of electricity Because the pigment is directly in contact with the air during storage and use, moisture absorption, oxidation, agglomeration and other phenomena will occur, and the direct use of black masterbatch will appear color spots on the surface of plastic products, the hue is dark, the color is easy to fade, and when mixing, it causes dust to fly, affecting the health of operators. The masterbatch is mechanically processed in the production process, the pigment is refined, and the pigment and resin carrier and dispersant are fully mixed to isolate the pigment from air and moisture, thereby enhancing the weather resistance of the pigment, improving the dispersion and coloring strength of the pigment, and the hue is bright.
2: Special masterbatch: is a masterbatch made by using the same plastic as the carrier according to the plastic variety specified by the user for the product. For example, PP masterbatch and ABS masterbatch are selected as carriers respectively. Universal masterbatch: also uses a certain resin (often PE with a low melting point) as a carrier, but it can be applied to the coloring of resins other than its carrier resin. 8. Universal masterbatch The universal masterbatch is relatively simple and convenient, but there are many shortcomings, and it is recommended that users choose a special masterbatch. The heat resistance level of the special masterbatch is generally compatible with the plastic used for the product, and it can be used with confidence at normal temperature. Only in the following cases, it will cause different degrees of discoloration, one is that the temperature is beyond the normal range, and the other is that the downtime is too long.
