Question

Differences between thermoplastcs and thermosetting plastics

Answer 1

Answer:

■ Thermoplastics :

Thermoplastics are the polymers which can be easily softened repeatedly on heating and hardened on cooling. Therefore, it can be used again and again. For example,

Polythene

Polyvinyl chloride

■ Thermosetting  :

Thermosetting polymers are those which undergo permanent change on heating. They become hard and infusible on heating and cannot be softened again. For example,

Bakelite

Melamine-formaldehyde

Answer 2

Explanation:

The primary physical difference is that thermoplastics can be remelted back into a liquid, whereas thermoset plastics always remain in a permanent solid state.Think of thermoplastics as butter – butter can be melted and cooled multiple times to form various shapes. Thermoset is similar to bread in that once the final state is achieved, any additional heat would lead to charring.
