A thermoset is a material that cures or sets into a given shape, generally through the application of heat. A cured, thermoset material will not remelt or otherwise regain the processibility it had before being cured. Curing changes the material forever.
A thermoplastic material softens (becomes pliable and plastic) when heated, but it does not cure or set. It can be reheated to be reformed.
