2.2. Thermal Properties

Try these first

1. 1.

   What property of plastics makes them good insulators?

   Hint

   Remember this property also helps conserve energy.

2. 2.

   What happens to thermoplastics when heated?

   Hint

   Think about the state change they undergo.

3. 3.

   What is the primary advantage of low thermal conductivity in plastics?

   • High strength
   • Low weight
   • Excellent insulation

   Hint

   Think about energy usage in buildings.

4. 4.

   True or False: Thermosetting plastics can be reshaped after they have cured.

   • True
   • False

   Hint

   Consider the behavior of each type when heated.

5. 5.

   Design a testing strategy for a new thermoplastic material intended for use in cold climates. What thermal properties would be most important and why?

   Hint

   Reflect on how these properties influence material performance under stress.

6. 6.

   Compare the environmental impacts of using thermoplastics versus thermosetting plastics in construction applications. Discuss in light of their thermal properties.

   Hint

   What happens to each material at the end of its life cycle?
