Study Finds Natural Pigments Survive PLA and PBS Extrusion but Fail Lightfastness
Can Natural Pigments Survive PLA and PBS Extrusion?
Executive Overview
Researchers produced color masterbatches from blue spirulina, yellow curcumin, red beetroot, and green chlorophyllin via twin-screw extrusion and compounded them into PLA and PBS at 2–6 wt%, maintaining mechanical performance and melt flow within close margins.
