Understanding Shore Hardness

Durometer or Shore Hardness is the scale on which the Density of Rubber and Polyurethane are measured. Although scarcely understood, for High Performance Rubber and Polyurethane Rollers it is worthwhile getting an understanding of how the scale works.

Defined by Albert Ferdinand Shore, who developed a device to measure Shore hardness in the 1920s. Shore developed three scales to measure a compounds density; Shore 00, Shore A and Shore D – we normally use the Shore A scale. It is critical to select the correct compound shore to ensure a high performance. We can supply you with a Durometer so you can determine the hardness of your existing rollers. This will assist our technicians develop a roller to match or outperform your current rollers.
