Explain why the following are made of thermosetting plastics.
(a) Saucepan handles
(b) Electric plugs/switches/plug boards
Answer
(a) Saucepan handles
Saucepan handles are made of thermosetting plastics because it resists fire and doesn't not get soft while heating.
It is a poor conductor of heat and hence doesn’t get hot even when the saucepan is heated
Thus, we use Thermosetting plastic such as Bakelite to make Saucepan Handles
(b) Electric plugs/switches/plug boards
Electric switches are made of thermosetting plastics because it resists fire and is a poor conductor of heat and electricity
Hence, we do not get a shock when electricity passes through the switch
Thus, we use Thermosetting plastic such as Bakelite to make Electric Plugs and Switches
