In the process of making a product, there are many factors that affect the quality of the finished product, whether it is machinery, what we eat, or what we usually use in daily life. Naturally, our color masterbatch is the same. What are the reasons for affecting the price of black masterbatch?
1、 Color divergence: raw carbon black is a very difficult and dirty mixture. It is dusty, light and fluffy. Unless large-scale treatment measures are adopted, it will dirty the machines and workers and make the working environment dirty.
2、 Rheology: if a color masterbatch itself has good dispersion, but it cannot flow into the material to be molded, the production effect is not ideal. Generally speaking, the priming resin used to produce color masterbatch has high rheology. In order to save costs, some color masterbatch manufacturers use reusable materials, waste or recycled materials as resin carriers.
3、 Compatibility: if the color masterbatch is produced from chips or recycled materials, it may contain pollutants or other non fusible polymers. This will cause some unforeseen and difficult constraints, wasting consumers' time and raw materials. At this time, the backing resin can be selected to produce high-quality color masterbatch, which has good compatibility in the melting process. Color masterbatch can be produced by LLDPE, LDPE, HDPE, PP, PS, San, PA and other materials.
4、 Stability: in today's international economy, it is necessary for international customers to have high requirements for the quality of color masterbatch and the stability of raw meal, which is also the fifth factor determining the quality of black masterbatch. One of the main manifestations of stability is the stable proportion of carbon black. If the percentage of carbon black fluctuates, the number of masterbatches to be melted is different, and it is impossible to produce products of the same color tone.
5、 Covering power: this factor is particularly important for color masterbatches used in waste or recycled polymers. In these cases, the role of black is to cover other colors in waste. The coloring ability of large particle carbon black is poor, and it is not easy to cover all other colors in the lower layer. As a result, the product only gets deviated colors. In the melting process, the ability to correctly select carbon black with high coloring ability to cover the existing color is the so-called covering power.
6、 Color shade: there are various types of carbon black on the market that can be used for coloring Color Masterbatch, but the colors and prices of various types are also very different. Large particle carbon black has lower coloring degree and different background color than small particle carbon black.
