The selection of raw materials and pretreatment is the first and crucial step in the preparation of environmentally friendly black masterbatch. These steps can effectively guarantee the quality and performance of environmental protection black masterbatch. It is conducive to the accurate production of high-quality environmental protection masterbatches.


The raw materials of eco-friendly black masterbatches include pigments, carriers and fillers. Environmental black masterbatches generally use carbon black as pigment, because carbon black has excellent coloring power, light stability and chemical stability. The types of carbon black are generally divided into ordinary pigmented carbon black, intermediate pigmented carbon black and advanced pigmented carbon black.


Our carrier generally choose composite carrier resin, LLDPE, LLDPE + EVA. carrier as the basic component of environmental protection black masterbatch, its role is to fix the pigment to ensure the dispersion of black masterbatch.


Common fillers are: calcium carbonate, barium sulfate and talc.


The pretreatment of raw materials for environmental protection black masterbatch needs to do the cleaning of raw materials, pretreatment of pigment, carrier treatment, mixing of additives, mixing of pigment and carrier, dispersion, filtration, cooling these major steps.
