When designing metal parts, it's important to specify their hardness. However, many engineers have only a shaky understanding of what hardness actually is, or how it's measured. There are good reasons ...

Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a ...

Plastic materials have been utilized in diverse products in a broad range of fields in recent years. Some of these include not only automotive parts such as bumpers, but also medical materials, daily ...

In materials science, the hardness of a material measures its resistance to deformation by indentation, scratching or other physical actions. By this metric, plastics and soft tissues are said to be ...

Measuring the “hardness” of soft, spongy elastomers—foams—is an inexact science. There is usually a surprisingly broad spread in the data normally provided by devices such as a durometer, a tool for ...

A gellike 30 Shore 00 Versaflex TPE is engineered to serve as ultrasoft cushions in bicycle seats, shoes, and furniture as well as nontacky grips on personal care products and sports equipment.
