The Heat Deflection Temperature

Perspective Meter:

easy or hard ?

basic or applied ?

In applications where polymers will be exposed to elevated temperatures, the heat deflection temperature is often used as a benchmark of high temperature performance. What is a precise definition of the heat deflection temperature? What properties of the polymer is it most closely related to?

Check your work carefully before taking a look at the answer.
