Thermoset versus Thermoplastic Polymers. By Jeffrey Gotro 1 Comment. Thermosets (or thermosetting polymers) are an important class of polymeric materials. The major use of thermosets is in applications where high temperature stability is required.hermoplastics are high molecular weight linear (or sometimes branched) polymers.

One way to think of an amorphous polymer melt like polystryene is a bowl full of cooked spaghetti.
