Several Factors Affecting the Quality of CaCO3 Filler Masterbatch

The plastic CaCO3 filler masterbatch is produced using carbon black. We mainly for you to determine the quality of plastic CaCO3 filler masterbatch factors, specifically the following aspects:

A, stability:

  In today's international economy, international customers on the quality of CaCO3 filler masterbatch, raw material stability and other requirements is absolutely necessary, which is to determine the quality of CaCO3 filler particles of the fifth factor. One of the main manifestations of stability is the steady ratio of carbon black. If the percentage of carbon black is fluctuating, then the amount of CaCO3 filler masterbatch that needs to be melted is not the same, and it is not possible to produce the same tone product;

B, 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

C, rheological:

  If a CaCO3 filler masterbatch itself has 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 CaCO3 filler masterbatch has a high rheological property. In order to save costs, some CaCO3 filler masterbatch producers use reusable materials, scrap or recycled materials as resin carriers;
D, color brightness:

  There are various types of carbon black on the market can be used for CaCO3 filler masterbatch coloring, but the various colors and prices are also very different. The large particles of carbon black have a lower color and a different background than the small particles of carbon black. Large particles of black color

Masterbatches are suitable for production such as garbage bags, but are not suitable for the production of those products that pay attention to aesthetics, such as television signs or places requiring UV protection such as agricultural films or external pipelines.

E, Coverage:

  This factor is particularly important for CaCO3 filler masterbats for waste or recycled polymers, in which case 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;
F, compatibility:

If the CaCO3 filler masterbatch is produced using chips or recycled material, it may contain contaminants or other non-meltable polymers. 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 CaCO3 filler masterbatch, masterbatch in the melting process have a good compatibility. High quality CaCO3 filler masterbatch can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials;
