9.2. Thermal Tests

Try these first

1. 1.

   What does the Vicat Softening Temperature indicate?

   Hint

   Think about when plastic starts to lose its shape.

2. 2.

   What is the purpose of Thermogravimetric Analysis?

   Hint

   Consider how materials react to heat.

3. 3.

   What does the Vicat Softening Temperature measure?

   • The temperature at which plastic melts
   • The temperature at which plastic begins to soften
   • The temperature at which plastic combusts

   Hint

   Think about the initial change in plastic due to heat.

4. 4.

   True or False: The Heat Deflection Temperature measures how plastic deforms under load.

   • True
   • False

   Hint

   Consider how weight affects material shape.

5. 5.

   A toy manufacturer wants to design thermal-resistant toys for summer use. Discuss which thermal tests would be most important and why.

   Hint

   Think about the temperatures expected in summer.

6. 6.

   An engineer is assessing a thermoplastic intended for automotive components. They find low TGA results. What implications does this have?

   Hint

   Balance performance under heat with longevity.
