The coefficient of Friction of a material is the measure of the sliding resistance of a material over another material. In the case of thermoplastics the mating part is normally steel. When multiplying the co-efficient of friction by the perpendicular force between the two mating sliding faces, this result is the force required to slide the components across each other.

Our ranking compares this “surface slipperiness” across our range of materials and is important when selecting products for use in dynamic applications.
