Pyrolysis　is　a　promising　technology　in　recycling　copper　from　enamelled　wires.　Nevertheless,　due　to　the　unclear　pyrolysis　characteristics,　the　sorting　of　enamelled　wires　is　deficient　in　the　pyrolysis　process.　This　work　systematically　investigated　the　pyrolysis　characteristics　of　polyester　enamelled　wire　(EPET),　polyester　imine　enamelled　wire　(EPEI)　and　polyurethane　enamelled　wire　(EPU).　The　decomposition　behaviours　showed　that　the　mass　loss　for　EPEI　and　EPET　was　around　1.9%,　while　it　was　about　1.5%　for　EPU.　The　pyrolysis　temperature　intervals　and　peaks　for　both　EPEI　and　EPET　appeared　in　the　range　of　320　-500　degrees　C　and　around　420　degrees　C,　while　it　was　in　a　larger　range　of　228　-657　degrees　C　for　EPU,　and　the　peak　was　about　280　degrees　C.　The　average　activation　energies　(E)　calculated　with　Flynn-Wall-Ozawa　(FWO)　model　demonstrated　that　EPEI　and　EPET　were　respectively　275.8　kJ/mol　and　296.9　kJ/mol,　while　it　was　194.2　kJ/mol　for　EPU.　TG-FTIR　results　proved　that　the-CH,-C--O,-CH2,　and-OH　were　the　main　functional　groups　in　the　pyrolysis　process　for　the　three　enamelled　wires.　Moreover,　Py-GC/MS　results　indicated　that　the　main　pyrolysis　product　was　benzoic　acid　for　EPET　and　EPEI,　while　it　was　not　observed　for　EPU.　The　pyrolysis　mechanism　displayed　that　the　kinds　of　pyrolysis　products　were　directly　related　to　the　connected　aromatic　functional　group.　The　complicated　pyrolysis　products　for　EPU　were　mainly　caused　by　the　generation　of　isocyanate.　Accordingly,　EPU　could　be　separately　pyrolyzed,　while　EPET　and　EPEI　were　suitable　for　co-pyrolyzed.　In　consideration　of　improving　pyrolysis　efficiency　and　reducing　energy　consumption,　the　classification　treatment　by　this　method　could　be　extended.
