The Shore durometer (pictured right) is a scale for measuring the hardness of a material, such as rubber, plastic, thermal  plastics (TPE), and rigid plastics. The term "durometer" is often used to describe a material's rating on the scale, for example “this material has a durometer of 60.”
  
It's worth noting, there are a variety of durometer scales since elastomeric and plastic resins vary over a wider range than one scale can accommodate. Download our comparison chart to see how these scales overlap.
 
Durometer hardness is one of many physical properties considered when selecting a material for a specific application. Beware of some common misconceptions. Durometer hardness is often inaccurately confused with the properties described below.

Technological advances in properties of soft, flexible foam and elastomeric materials have continued to advance. These thick, soft, flexible foams and elastomers are ideal materials for sealing, gasketing and cushioning across many industries and applications. They compress, form to irregular surfaces, bend, and flex within an application without damage or de-lamination, but from the perspective of the die cutter, may also introduce challenges when trying to achieve the tight dimensional tolerances common in metal and plastic-molded parts.
