Welcome to ISG Rubber Durometer Scale Section

A durometer scale is a type of measurement for rubber material hardness. The rubber durometer chart below gives you an idea of the rubber hardness that you want for your application. Generally, most rubber materials fall under the rubber durometer scale of Shore A.

A rubber durometer of Shore 70A is the most commonly chosen material hardness for all applications.
