4 cards from this section. Quick, good the night before a test.
What does tensile strength measure?
Think about what happens to a rubber band when it is stretched too far.
What is the glass transition temperature (Tg)?
Recall the temperature where you might see a change in ice or butter.
What is the melting temperature (Tm) of a polymer?
Think about ice turning to water.
True or False: Thermosets can be remolded after curing.
Remember how glue hardens and can’t be reshaped.
A new polymer has a Tg of 100°C and a Tm of 250°C. Discuss how you would approach processing this polymer for manufacturing and the implications of its properties.
Consider the thermal properties and how that influences material handling.
Investigate how increasing crosslink density can alter the properties of a thermoset polymer. What would be the benefits and drawbacks?
Think about how rubber bands behave differently from hard plastics.
