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.


Data sheets are routinely relied upon, yet the data they provide is limited in scope and can lead to incorrect conclusions.

MATERIALS: The Problems with Single-Point Data

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.
