Temperature dependence of kinetic friction: A handle for plastics sortation?

Abstract:Sortation is a crucial step in the mechanical recycling of post‐consumer plastics (PCR) whereby properties such as density or spectral signature are used to separate plastics. However, it is difficult to sort polyolefin flakes at high throughput by these properties. We ask whether the frictional properties of plastics as a function of temperature may be used as an alternate sorting property. However, fundamental studies of friction at temperatures near their melting points are limited. Here we measure the temp… Show more
