Polymer properties are not constant as a function of temperature, and even small temperature changes can affect properties.


Engineers who are used to working with metals are surprised that plastics cannot operate as close to their yield points as can metals. The yield point is not enough to tell you how the material reacts to stress.

MATERIALS: The Problems with Single-Point Data

In plastics, notched Izod and Charpy test results have been complicated by the way they are reported.

MATERIALS: The Problems with Single-Point Data
Properties are generally provided at a single temperature on a data sheet. But do those properties stay the same with changing temperatures? Of course not.
