Rubber Materials Selection


This course explains how the unique characteristics of elastomers allow them to fulfill some functions much better than other materials.

The families of elastomer types are explored, showing how they can be similar in some ways, yet very different in properties. These properties may be independent of each other, or correlate positively sometimes, or negatively at other times. This shows why finding an exact balance of several desirable properties for a given application may be difficult if not impossible. The pitfalls of making a poor choice of an elastomeric compound are described.

Exactly how the choice of elastomer type can be approached is explained, using a series of questions about the functional goal of the product and the environment in which it must operate. Practical exercises are conducted to give attendees some real experience in the selection process.
