Questions & Step-by-Step Solutions

Which of the following is a characteristic of thermosetting polymers?
Correct Answer: They harden permanently after being set.
  • Step 1: Understand what thermosetting polymers are. They are types of plastics that, once they are set into a shape, cannot be melted down again.
  • Step 2: Learn that when thermosetting polymers are heated, they do not become soft or melt like some other plastics. Instead, they become harder.
  • Step 3: Remember that this hardening is permanent. Once they are set, they cannot be reshaped or melted.
