   Hint

   Think about how heat affects their structure.

2. 2.

   What is an example of a thermosetting plastic?

   Hint

   Remember, it's often used in electrical applications.

3. 3.

   What is a characteristic of thermoplastics?

   • They cannot be reshaped
   • They can be reshaped
   • They are always opaque

   Hint

   Remember their properties relating to heat.

4. 4.

   Are thermosetting plastics re-moldable after they set?

   • True
   • False

   Hint

   Think about what ‘setting’ means in their context.
