Ultra-low-density neat HDPE foams via steam-assisted scCO2 foaming

High-density polyethylene (HDPE) is difficult to foam because of its high crystallinity and low melt strength, and most strategies require crosslinking, blends or fillers. Here, we investigate an additive-free route based on one-step batch foaming with supercritical CO 2 (scCO 2...
