Thermoplastic vs. Thermoset: Why Recycling Approaches DifferThermoplastics: Linear polymer chains with weak intermolecular bonds. Can be repeatedly melted and remolded, enabling straightforward mechanical recycling.Thermosets: Network polymers with a high level of cross-linking and strong chemical bonds. Once cured, the material cannot be re-melted. This irreversible cross-linking requires special···
