  • PROCESS AND SYSTEM FOR RECYCLING EPOXY THERMOSETS
    Publication number: 20240199841
    Abstract: The present invention relates to a process and system for recycling epoxy thermosets, containing cleavable bonds, said process using an acid solution to dissolve the epoxy thermoset and devolatizing the acid solution from a thermoplastic acidic mixture to produce the thermoplastic component. The process allows recovery of a recyclable thermoplastic component and optionally a recyclable reinforcement matrix component. The process comprising dissolving the epoxy thermoset in an acid solution under heated conditions resulting in a thermoplastic mixture; optionally filtering the thermoplastic mixture to separate out a reinforcement matrix component from a thermoplastic solution; and devolatizing the thermoplastic solution to obtain a recyclable thermoplastic component.
