Significant research efforts are being pursued by numerous plastic foaming industries
towards the transformation of macrocellular polymer foam to microcellular and imminent …

Silicone rubbers were successfully foamed by supercritical carbon dioxide (SC CO 2).
Samples were precured and fully cured before and after the basic foaming process with SC …

Rheological properties, determined by cross-linked structure of silicone rubber and
plasticization of CO 2, would affect the cell nucleation and the cell growth during …

Porous polymer with lower density is more favorable for practical thermal insulation. In this
work, a judicious combination of mechanical mixing and supercritical carbon dioxide …

Ultra-low density porous polystyrene monoliths have been prepared via using water/styrene
gel-emulsions, which were stabilized by a low-molecular mass gelator (LMMG), as …

Silicone rubber foam was prepared by direct rapid depressurization foaming process using
supercritical CO 2 as foaming agent. It was found that under high temperature and pressure …
