Abstract
Friction modifiers are composition which modify the coefficient of friction between surfaces to which the friction modifier is applied. They are similar in nature to lubricants but have different characteristics in certain respects. The invention relates particularly to solid friction modifiers which may be rigid or flexible. These friction modifiers comprise 20-80% by weight of a polymer medium, 5-20% by weight of a solid lubricant and 15-60% by weight of a friction enhancer. The composition produces a coefficient of friction which rises to above 0.20 at creepage level up to 2.5% between steel bodies in rolling-sliding contact lubricated using the composition.
