Any closed-cell polyolefin foam production tends to achieve the highest possible cell size
distribution uniformity, cell size reduction, and cell density augmentation. However, the …

Structural foams offer numerous advantages over their solid counterparts, including greater
geometrical accuracy, the absence of sink marks on the final product's surface, lower weight …

The use of polymer microspheres for producing fine-cellular foams is a new development in
rotational molding. In previous studies, some reduction in mechanical properties has been …

Mold filling plays a crucial role in determining the cells' structural morphology and uniformity
in high-pressure foam injection molding. This process affects the formation, deformation, and …

Many efforts have been made to obtain uniform cell structures from foam injection molding
techniques. However, cell nucleation mechanism and complex dynamics during the cell …

This article presents an extrusion-based, open-cell foaming process using thermoplastic
polymers such as polystyrene (PS) and polycarbonate (PC) with supercritical CO2. Our …
