Correct Answer - Option 4 : Bakelite

The correct answer is Bakelite.

  • Bakelite is the thermosetting plastic.
  • The material becomes very rigid and irreversible in nature when it is heated.
  • Thermosoftening (also called thermoplastics) are plastics that will soften when heated and can be reshaped.
  • Thermosetting plastics are plastics that do not soften on heating.
  • They are used when resistance to heat is important (eg kettles, plugs, laptop chargers, etc).
  • Thermosets are used to produce electrical goods and components, including insulators and panels.
  • These are used to produce construction equipment panels. Because they are heat resistant, they are used to produce heat shields. In automobiles, thermosets are used to produce brake pistons.
