Abstract

Frictional forces (for temperatures less than the melting or devitrification temperature) and shear stresses are keys to the solids conveying and melting processes in plasticating, single-screw extruders. For most processes, the shear stress at the polymer-metal interface, however, is unknown. This paper presents shear stresses and melting fluxes for three polycarbonate (PC) resins with different melt flow rates. The data are related back to the extrusion process.
