High gloss weather-resistant black masterbatch is a functional masterbatch based on polyethylene (PE) with carbon black and calcium carbonate fillers, manufactured through a rationally designed and processed process. Its carbon black content is approximately 43% ± 2%, maintaining high coloring performance while imparting excellent weather resistance and structural strength to finished products, meeting the dual demands of appearance and performance in various applications. This masterbatch exhibits stable dispersion during the compounding and injection molding of engineering plastics, ensuring uniform distribution of carbon black throughout the matrix, effectively ensuring high gloss and smoothness in finished products. It is suitable for injection molded parts requiring high aesthetic standards.
During use, this high-gloss weather-resistant black masterbatch can be directly added to raw materials for production. The recommended addition level is 1-3%, ensuring both aesthetic quality and enhanced durability. Its excellent dispersion properties not only reduce surface defects caused by pigment agglomeration but also improve the product's weathering stability under conditions of light, humidity, and temperature fluctuations, thereby extending the product's service life. It also enhances the mechanical properties of molded parts, making it suitable for applications requiring both structural strength and aesthetic appeal.
