Question:
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?
Solution:
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.
Thermoplastics —–>Polythene and PVC ‘
Thermosetting plastics —–> Bakelite and melamine
