Is Bakelite a thermosetting plastic or a thermo plastic?
Bakelite is a thermosetting plastic. Unlike thermoplastics, which can be melted and reformed multiple times, thermosetting plastics like Bakelite undergo a chemical change when heated, permanently setting their shape. Once cured, Bakelite cannot be remolded or reheated without undergoing degradation. This property makes it suitable for various applications, including electrical insulators and household items.
Why is bakelite used to make electrical switches and handle of utensils?
