Question

Explain the difference between thermoplastic and thermosetting plastics?​

Answer 1

Answer:

thermoplastic-

Thermoplastics are defined as polymers that can be melted and recast almost indefinitely. They are molten when heated and harden upon cooling. When frozen, however, a thermoplastic becomes glass-like and subject to fracture.

thermosetting plastic-

Thermosetting plastics are made up from long chains of molecules that are cross-linked. They have a very rigid structure. Once heated, thermosetting plastics can be moulded, shaped and pressed into shapes. Once set they cannot be reheated since they are permanently set.

Answer 2

$\large\underline{\sf{\green{Thermoplastics :-}}}$

• They are plastics which gets melted on heating.
• These plastics can be moulded again and again.
• Examples :- PVC(Polyvinyl chloride), Polythene..

$\large\underline{\sf{\green{Thermosetting \: plastics :-}}}$

• These plastics doesn't gets soften much on heating and can maintain their shape even at high temperature.
• These plastics can't be remoulded easily.
• Examples :- Melamine, Bakelite..
