Rubber Hardness Chart

Educating Rubber User

Welcome to our 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. Thus, if you need a rubber or O-ring durometer that feels like a running shoe sole, review our rubber hardness chart below, then pick Shore 70A. A rubber durometer of Shore 70A is the most commonly chosen material hardness for all applications.

  • a. Shore 20A = Rubber Band

  • b. Shore 40A = Pencil Eraser

  • c. Shore 60A = Car Tire Tread

  • d. Shore 70A* = Running Shoe Sole

  • e. Shore 80A = Leather Belt

  • f. Shore 100A = Shopping Cart Whee
