The webinar dives into the mechanisms behind caking and poor powder flow, explaining how moisture uptake, particle size, and surface structure influence powder performance. It highlights how Evonik’s functional silicas act as effective flow aids and anti-caking agents, creating a microstructure that keeps particles separate and free-flowing, even under challenging humidity conditions. Practical examples illustrate how adjusting silica grade and concentration can fine-tune behaviour across different base materials, such as maltodextrin or protein powders.
