Question

Both bakelite and polythene are platics , but they still are different. Why?

Answer 1

Bakelite is a thermosetting plastic material, does not conduct electricity, therefore, it can be used in insulating materials. Bakelite is resistant to heat and chemical actions and also it is non-flammable.

On the other hand,

Polythene is a thermoplastic which means it can be reheated repeatedly without undergoing any chemical change. This allows them to be reshaped or recycled into new materials.It is flammable.
Hope it helps.
