Selective oxidative devulcanization of hydrosilylation-cured silicone elastomers: enhanced circularity

Abstract

In commerce, silicone elastomers are typically cured by platinum-catalyzed hydrosilylation or radical induced crosslinking (High Temperature vulcanization (HTV)), both of which lead to crosslinks comprised of 2 or 3 carbon...

Converting commercial-grade silicone into a vitrimer using elemental sulfur

“…This recycling approach is energy-intensive, has low production efficiency, and can lead to additional environmental pollution. 14–16…”
