Characterization of Carbon Black Composites

Highlighting Thermal Conductivity and Dynamic Mechanical Analysis (DMA)


Thermal conductivity is a crucial property of carbon black (CB). When applied as a filler material, CB acts to improve heat dissipation through the formation of thermally conductive networks. This is particularly relevant to applications such as tire (rubber) manufacturing and thermal management of batteries and electronics. In tire manufacturing, CB is commonly used as a reinforcing filler. Its high thermal conductivity helps conduct heat away from the tread and belt area of the tire improving overall performance. An application highlight on CB/rubber composite design from Laval University will be featured discussing the influence of a hybrid filler on thermal conductivity.

While thermal considerations are important, one of CB’s original uses was as a reinforcing filler to increase mechanical performance.  In the tire industry, CB can be tailored for increasing handling, lower rolling resistance and increasing sidewall strength.  CB can also be used to improve durability in the most extreme cases by reducing tear. This presentation will cover the different characterization methods through Dynamic Mechanical Analysis and showcase an application highlight on the effect of carbon black on the fracture and fatigue of rubber materials.

Join us for this webinar, where we will highlight thermal conductivity testing on various novel CB composite materials using C-Therm’s Trident platform as well as the benefits of using Metravib’s high-force DMA to characterize filler interactions, mechanical performance, and crack growth.
