Understanding Polymers: Thermoplastic vs Thermosetting

The main difference is in the rigidity of the molecular chains. Thermoplastic polymers have long molecular chains that are not rigidly connected, while thermosetting polymers have tightly connected molecular chains.

The rigidity of molecular chains in thermoplastic polymers allows for good ductility and formability, while in thermosetting polymers, it makes them stronger but more brittle.

Thermoplastic polymers are shaped by molding their molten form.
