White carbon black has a series of unique properties that make it shine in many fields.


In terms of physical properties, it is a porous substance with a large specific surface area that allows it to adsorb other molecules. Taking gas-phase white carbon black as an example, its huge specific surface area makes it excellent in thickening, thixotropy, and other aspects. White carbon black is lightweight, with a relative density generally between 2.32-2.65. Moreover, it also has good electrical insulation properties, which have important applications in fields such as the electronics industry.
In terms of chemical properties, the hydroxyl groups on the surface of white carbon black give it a certain level of chemical activity. It can undergo chemical reactions with certain substances, such as in the process of rubber reinforcement, the hydroxyl groups on the surface of white carbon black can interact with rubber molecules, thereby enhancing the performance of rubber. White carbon black also has good chemical stability. In general acidic and alkaline environments, it will not easily undergo chemical reactions and can maintain its own structural and performance stability. This also makes it applicable in many systems that require chemical stability. It is soluble in caustic soda and hydrofluoric acid, but insoluble in other acids, water, and various common solvents. This special solubility also provides the possibility of its application in specific chemical processes.
