Durometer is the measure of hardness of an elastomer, similar to Rockewell hardness for steel. Durometer is a measure of indentation of a shaped pin into the elastomer surface at a given load. Shore A, D and 00 are the most commonly used scales; however, other scales such as B, C, and O are occasionally used.
Durometer is one of the most critical properties to consider when selecting the right polyurethane for durability and abrasion characteristics. The higher the number on each scale, the harder the urethane will be. Harder durometers exhibit better better mechanical properties as well as better abrasion and chemical resistance than the softer durometers.
