What Is the Coefficient of Friction of Rubber?

The coefficient of friction of rubber depends upon the surface in contact with the rubber. Rubber against rubber results in a static coefficient of friction of 1.15, whereas rubber against asphalt results in a static coefficient of friction of 0.9.

It is important to note that in addition to the coefficient of friction, depending upon the materials that are in contact, this coefficient is different for materials that are in motion. A static coefficient of friction describes two materials that are in contact with each other but are not in motion. A kinetic coefficient of friction describes two materials that are in contact with each other and are in motion. A kinetic coefficient of friction is typically less than a static coefficient of friction.
