Difference between Thermoplastic and Thermosetting?

Answer

The essential difference between thermoplastic and thermosetting is that thermoplastic remains permanently fusible after they process of forming them and hence they soften and finally melt when heat is applied. Themosetting on the other hand involves the process of forming polymers that do not soften, and that only char and break down at very high temperatures.

Thermoplastic polymers soften and melt on heating. They can be remoulded recast, reshaped and are less brittle and soluble in some organic solvents. They also usually have linear structures. Thermosetting polymers do not soften on heating but rather become hard in the case of prolonged heating. They are more brittle and insoluble in organic solvents and more brittle and insoluble in organic solvents. They have three dimensional cross linked structures. These can not be remoulded or reshaped.
A thermoplastic, also thermosoftening plastic, is a polymer that liquidates when heated and becomes solid when cooled sufficiently. A thermosetting plastic, also known as a thermoset, is polymer material that has cures that are irreversible. The cure may be done through heat, through a chemical reaction or by use of an electron beam.
Thermoplastic are brittle and soluble in some organic solvents while thermosetting are more brittle and insoluble in organic solvents also thermoplastic soften and melt on heating while thermosetting do not soften on heating but rather become hard in case prolonged heating is done these start burning.
