Impact Strength Characteristics of Polymers

Of the many properties of a plastic that influence its choice for a particular article or application, the ability to resist the inevitable sharp blows and drops met in day-to-day use is one of the most important. The prime object of impact testing should be to give a reliable guide to practical impact performance. However, the performance requirements and the design and size of article can vary considerably. The method of fabrication can also vary, and because all these factors can influence impact performance, a reasonably wide range of data are required if most of these eventualities are to be covered and materials and grades compared sensibly.
