5. The material difference between the two is that thermoplastics can be remelted , while thermoset plastics remain in a permanent solid state once hardened . Answer. The two plastics classification are thermoplastic and thermosetting: The major difference between the two plastic categories; Thermoplastics can be melted after shaping and remolded or reprocessed, where Thermosetting plastics cannot be melted after cooling; they are only molded when first prepared, and can’t be reprocessed. The key difference between thermoplastic and thermoset is that it is possible to melt thermoplastic into any shape and re-use it whereas thermosets have a permanent shape and are not recyclable into new forms of plastic. 3.
