“…Cellular plastics have been extensively applied in packaging, − transportation, − engineering, , and aircraft , due to their outstanding mechanical performance, shock absorption, thermal insulation, and low density. In particular, epoxy cellular plastics, , one of the most commonly used cellular plastics, have drawn considerable attention for their excellent mechanical properties. Especially, epoxy cellular plastics with excellent compression resistance, low weight, and thermal stability are broadly applied in marine equipment, aircraft, − and vehicles. − During the past decades, many foaming technologies, such as chemical, solid-state, and CO 2 foaming, , have been developed to manufacture epoxy cellular plastics in the industry.…”
