The functional differences between the various compounds can be summed up by observing the coefficient of friction as a function of operating temperature: the RC compound (organic Racing, where 350 - 450°C operating temperature can be considered normal conditions) has a very high coefficient of friction in hot conditions, whereas road compounds (such as sintered road SA) are designed to work best at medium/low temperatures, and precisely around 300°C. Consequently, the latter, if used on track and therefore overloaded, will be affected by the "fading" effect, i.e. the degradation of the coefficient of friction: indeed, above a certain temperature, they will tend to.
