what are the differences in the structureand properties of thermoplastics and thermosetting plastics ?

Answer 1

in terms of structure, both have very long molecular chains. however, thermosets may possess "cross-linked" or networked structures.

thermoplastics are called as such, because they can be formed or deformed at high temperatures, especially above their "glass transition temperature", or above melting temperature.

At high temperatures thermoplastics soften or become less rigid.

Thermosets like epoxy will harden upon application of heat. (A process called "curing").

However, thermosets will degrade at very high temperatures. (they don't have a melting point or glass-transition temperature).

-- those are the main differences. good day ;)
