Carbon black coloring melanin can often better to plastics coloring, can be used carbon black pigment or coloring characteristics according to physical and chemical properties, carbon black coloring species of choice are basically finished with the black level must be reached. With very fine carbon black pigment can complete degree requirements are particularly high black coloring; PE garbage bags, plastic bags, products of cable materials with only moderate levels of blackness, you can use a lower specific surface area, large silica which company high structure carbon black varieties; Plastic color, small errors that occur when carbon black weighing and batching will result in a clear color, low silica Which price, therefore, should adopt a larger particle size, silica, coloring poor low carbon black pigment, so the amount of carbon black may be slightly larger, white carbon Which is guaranteed, weighing error relatively small, and there is good dispersion, low-cost advantages. Carbon black in the plastics industry application before selecting, you must determine its use, such as for coloring, anti-ultraviolet light, or a conductive and so on. Which silica guaranteed | Weifang Fuyuan (certified) | silica provided by Weifang Fuyuan Environmental Technology Limited.
