The basis of producing color masterbatch is mixing the primary resin with other substances, for example fillers, pigments and additives. Similarly, to produce black masterbatch, manufacturer firstly mix black carbon powder, base resin and other additives according to the well investigated formula, then mix well by mixer at high speed for about 10 minutes. The mixture after being mixed will be passed through the extruder to pour into a sheet, then be cooled and then passed through a cutter to cut into masterbatch particles.
The finished masterbatch is then mixed with primary plastic granules and other additives into a mixture of plastic materials. This mixture will undergo different processing technologies depending on the product shape that customers require (injection molding, extrusion, blowing film …).
In response to the different requirements of black Masterbatch, we studied and developed five different types of black master batch based on black carbon proportions ranging from 20 to 50%.
- UB 20 includes 20% of black carbon
- UB 30 includes 30% of black carbon
- UB 40 consists of 40% of black carbon
- UB 50 consists of 50% of black carbon
