Solution:

Thermosetting plastic consists of chain of the molecules which are cross-linked, with each other when heated. When thermosetting plastics cross-link, the molecules create a permanant, network which is a D structure and can be considered one giant molecule. Once cured, thermosetting plastic cn not be remelted, in the same way that cured concrete cannot be reset.
