Material Characterization of Lignin‐Filled Polypropylene Composites
Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.Ground and spray‐dried lignin powders are compared as fillers for polypropylene composites. Differences in powder preparation methods are associated with differences in powder characteristics and composite behavior after melt compounding. Spray‐dried lignin produces smaller particles and fewer large agglomerates, while a 5 wt% lignin loading provides a
