One. Stability should be shared.
In today's international economy, it is certainly necessary for international customers to have high demand for the quality of masterbatches and the stable function of raw materials, which is also the fifth factor that determines the quality of black masterbatches. One of the first manifestations of stability is the stable share of carbon black.
Two. The brightness and darkness should be clear.
One element that determines the quality of black masterbatch at the end is the brightness of the color. There are various types of carbon black in the mall that can be used to color masterbatches, but the various colors and quotations are also very different. Large-grain carbon black has lower coloring and different base color than small-particle carbon black.
Three. The classification and application scale of carbon black in general.
SRF carbon black is typically used in garbage bags that do not require strong coloring power, high masking power or UV maintenance. The color tends to be gray-blue, cheap to offer, and relatively easy to disperse, so small masterbatch manufacturers who only have a single or double helix extruder will choose this carbon black. HAF carbon black has half the size of SRF carbon black particles, but the coloring intensity is twice that of it.
Four. Be mobile.
The third factor that determines the quality of black masterbatches is rheology and mobility. If a masterbatch itself has outstanding dispersion, but it cannot enter the guess of the material to be molded, the role of the production is not aspirational. In general, priming resins used to produce masterbatches have high rheology. In order to save money, some masterbatches are produced using reused materials, waste or recycled material as resin carriers.
Five. Compatibility should be great.
Compatibility is the fourth element that determines black masterbatch quality. If a masterbatch is produced from chips or recycled material, it can be rich in contaminants or other polymers that do not melt. This leads to unexpected and difficult hassles, wasting the moment and material of the end consumer. At this time, the priming resin can be selected to produce high-quality masterbatches, and the masterbatches have outstanding compatibility during the melting process.
Six. The dispersion should be high.
Black masterbatches are produced using carbon black. Raw carbon black is a very difficult and dirty mixture that is dusty, lightweight, and loose. Unless large-scale disposal is used, it will stain machines and workers and make the working environment dirty. Because of this, casters choose a resin carrier, that is, a black masterbatch, to complete the pre-dispersion of carbon black.
Seven. The concealment should be strong.
The second element that determines the quality of black masterbatches is masking power, which is particularly important for masterbatches used in waste or recycled polymers, where black acts to mask other colors in the waste mix. The coloring of large-grain carbon black is poor, and it is not easy to cover up the color of everything else at the base layer, and the product at the end of the result only gets the color that is deviated.
