Floor Slip Ratings - R9 to R13 - ABC - Floor Safety

Friction is the resistive force to motion and is generally defined as 'that force that acts between two bodies so as to resist their sliding over one another'. A floor with a high friction capability will provide enough 'grip' in most circumstances to prevent a person

Friction Modifier Additives | SpringerLink

4/9/2015 · The need for energy efficiency is leading to the growing use of additives that reduce friction in thin film boundary and mixed lubrication conditions. Several classes of such friction modifier additive exist, the main ones being organic friction modifiers, functionalised polymers, soluble organo-molybdenum additives and dispersed nanoparticles. All work in different ways. This paper reviews

Friction of Polymers Sliding on Smooth Surfaces

14/12/2011 · Friction plots of polymers sliding on smooth metal surfaces are generally characterized by two regions of distinct dependency on the normal load, with low sensitivity at low stress levels followed by a sharp change in the rate of decrease of friction with increasing pressure at levels above the plastic flow limit of the polymer. A simplified model is proposed to describe this behavior which
