PVC (Polyvinyl Chloride) is a thermoplastic and is used for making toys, chappals etc. Bakelite is 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?        

Answer:

     Thermoplastics get deformed easily on heating and can be bent easily on heating. On the other hand, thermosetting plastics when moulded once cannot be softened on heating.                                                                     The examples are as follows:

(i) Thermoplastics: Polythene and PVC

(ii) Thermosetting plastics: Bakelite and Melamine.
