Important factors affecting the quality of black masterbatch

Coverage is one of the important factors that determine the quality of black masterbatches. This factor is especially important for color masterbatches used in waste materials or recycled polymers. In these cases, the role of black is to cover other colors in the waste materials. Large Granular carbon black has poor coloring ability, it is not easy to cover all other colors of the lower layer, and the final product only deviates from the color. 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 ability.

Rheology and fluidity are also an important factor in determining the quality of black masterbatch. If the masterbatch itself has good dispersion, but cannot flow into the required molding material, the production effect is not ideal. Generally speaking, use The primer resin used in the production of masterbatches has high rheology. In order to save costs, some masterbatch manufacturers use reused materials, waste or recycled materials as resin carriers. If the rheology is not good, the foundry will be in the cycle There will be trouble in time and appearance processing. It is worth noting that if the dispersion and rheology are not high, some end users will make up for it by increasing the dilution ratio, but this will only increase the cost of using the masterbatch. The dilution ratio is the smallest The color masterbatch can produce uniform, good dispersion black.

Dijiu High-tech Materials (Nantong) Co., Ltd. was established in 2006. It is an enterprise that produces plastic masterbatches with research and development as the core. At present, the company has 12 twin-screw production lines with an annual production capacity of more than 50,000 tons. The existing plastic masterbatches , Degradable masterbatches, plastic modified granules, monochrome masterbatches, plastic and chemical fiber functional granules, special effects and special functional granules series products, used in new energy vehicles, home appliances, consumer packaging, fabrics, films, medical and other industries, Products are sold to more than 30 provinces and cities, Southeast Asia, Europe, the United States and other regions.
