Plastic, as an important industrial material, has the advantages of light weight, corrosion resistance, and easy processing, and is widely used in various fields. However, certain properties of plastics such as hardness, rigidity, and heat resistance still need to be improved. White carbon black, as an excellent plastic filler, plays an important role in plastic modification. This article will explore the application of white carbon black in plastic modification.


1、 Improvement of Physical and Mechanical Properties of Plastics by White Carbon Black


Adding white carbon black to plastics can significantly improve their hardness, rigidity, and wear resistance. The high specific surface area and porous structure of white carbon black enable it to form good bonds with plastic molecules, enhance the internal structure of plastics, and thus improve their physical and mechanical properties. In addition, white carbon black can improve the impact resistance and creep resistance of plastics, making them more suitable for manufacturing components that can withstand large loads.


2、 The Influence of White Carbon Black on Plastic Processing Properties


The addition of white carbon black also has a certain impact on the processing properties of plastics. Moderate amount of white carbon black can improve the flowability and melt strength of plastics, making them easier to process and shape. However, excessive white carbon black may increase the melt viscosity of plastics and make processing more difficult. Therefore, it is necessary to reasonably control the amount of white carbon black added in plastic modification.


3、 Application of White Carbon Black in Special Plastics


In addition to general plastics, white carbon black also plays an important role in some special plastics. For example, in conductive plastics, white carbon black can serve as a carrier for conductive fillers, improving the conductivity and stability of conductive plastics; In flame retardant plastics, white carbon black can work synergistically with flame retardants to improve the flame retardant and smoke suppression properties of plastics.


4、 The Future Trend of White Carbon Black Plastic Modification


With the advancement of technology and the increasing demand for environmental protection, the application of white carbon black in plastic modification will become more extensive and in-depth. In the future, researchers will focus on developing new types of white carbon black materials to improve their compatibility and dispersibility with plastics; At the same time, the synergistic effect of white carbon black and other modifiers will also be explored to prepare plastic composite materials with higher performance.
