Both cof and wear rates of the epdm mixes strongly depended on the test configurations.
Epdm rubber has a common use as seals in automobiles.
A similar tendency was found for the cof in rop tests.
Static friction is friction between two or more solid objects that are not moving relative to each other.
μ static μ s or kinetic μ k frictional coefficient.
The friction values used in the material interaction table are generalized values based on the following references.
The coefficient of frictions cof and specific wear rates of the epdms were determined.
The rubber stocks were prepared in a laboratory internal mixer and the curatives were introduced on a laboratory open mill.
The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it.
Further aim of this work was to investigate on how the friction and wear properties of the epdm rubbers depend on the configuration of the testing rigs.
Fric tion force normal load and coefficient of friction cof were determined.

The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction.
The resistance to polar substances and steam are also good.
The maximum force of static friction can be calculated by multiplying the normal force by the coefficient of friction specific to the pair of materials in contact.
