Abstract
The external coefficient of friction of the polymer pellets at the inner barrel surface, as well as at the screw surface is a decisive factor for solids conveying in single screw plasticizing units. Besides other parameters, like the screw geometry and the processing conditions, they affect the pressure build up behavior and the temperature development in the solid plug. A new apparatus for analyzing the frictional behaviour of polymer pellets at the screw surface is presented in this paper. The external coefficient of friction between 3 different polymers and 3 different Metal surfaces are presented in this paper.
