    What has the highest coefficient of kinetic friction, steel on polyethylene, rubber on polyethylene, or polyethylene on polyethylene?

    That would be infinity ... ie. complete classical adhesion.
    The "coefficiant of friction" is just a model.

    Commonly known as the ' coefficient of fiction ' in engineering .

    Actual friction forces as measured for real sliding surfaces are often far different from calculated values .
