Abstract Plastic recycling is a critical step toward improving waste management and achieving economic recycling. Here, thermoset crosslinked by guanythiourea structure (GTUH network) reported, that addresses the issue of thermosets serial hybridization thiourea guanidine urea. The dual dissociative dynamic exchange reaction guanamine urea thiourea, combined with non‐covalent hydrogen bonding interactions, endows network rapid relaxation ability. GTUH networks, in particular, can be recycled through continuous extrusion processing due to multiple reversible mechanisms, as opposed hot pressing alone. Even if reprocessed pressing, only 5 min at 140 °C 10 MPa are required. oxidation enhancement mechanism contributes maintaining or even mechanical properties network. Moreover, reactions allow for closed‐loop chemical Research into recyclable carbon fiber‐reinforced composites indicates promising potential applications this material circular economy resources.
