PVC (polyvinyl chloride) is a thermoplastic and is used for making toys, chappals, etc. Bakelite is a thermosetting plastic and is used for making electrical switches, handles of various utensils, etc. Can you write the major difference between these two types of plastics?

The major difference between the two plastics is that thermoplastics (like polythene, PVC) get deformed easily on heating and can be bent easily on heating.

On the other hand, thermosetting plastics (like bakelite, melamine) once moulded cannot be softened on heating.
