How does carbon black structure affect dispersion rate? - Phillips Carbon Black Limited

How does carbon black structure affect dispersion rate?


Higher structure carbon blacks are generally more easily dispersed than low structure carbon blacks of similar surface area. A high structure carbon black is one in which the aggregates are composed of many primary particles clustered together with considerable branching and chaining. As a result, the aggregates pack more poorly reducing the inter-aggregate attractive forces. Low structure carbon blacks are more compact, allowing closer packing and thus greater inter-aggregate attractive forces which makes dispersion difficult. However, while an increased supply of energy is required to disperse lower structure carbon blacks, their higher density allows them to ‘wet’ or incorporate easily due to less occluded air to displace.
