Epoxy resin serves as an essential insulating material in electrical applications. Its persistent crosslinked network structure impedes effective recycling

leading to significant environmental burdens and resource depletion. Epoxy Vitrimer

however

exhibits thermoplastic properties due to bond exchange reactions. This characteristic provides a novel approach for recycling thermosetting epoxy materials. We systematically investigated the effects of time-temperature synergy on the electrical

thermal

and mechanical properties of recycled Vitrimer resin. The results indicate that

as the thermal compression recycling temperature increases

the electrical and mechanical properties of the recycled samples initially improve and then decline

while the thermal properties remain largely unaffected. With prolonged time

the electrical and mechanical properties show an upward trend

but a saturation phenomenon is observed. Again

the thermal properties exhibit no significant changes. Under synergistic time-temperature conditions

the interfacial bonding of regenerated samples adheres to an Arrhenius-type time-temperature superposition principle. This behavior originates from their concerted modulation of molecular chain reorganization efficiency during hot-pressing

collectively governing the performance evolution of recycled materials. Optimizing time-temperature conditions ensures sufficient reactions while preventing thermal degradation

achieving optimal electrical

mechanical

and thermal properties. This study provides theoretical and practical insights into improving the thermal compression recycling of epoxy-anhydride Vitrimer

enhancing its recyclability and advancing high-performance renewable polymer materials.
