EXTRUSÃO DE TERMOPLÁSTICO: estudo do comportamento do termoplástico vulcanizado (TPV), como fluído, no processo de extrusão com extrusoras mono-rosca tipo barreira

Abstract

The present work reports the behavior of the TPV (vulcanized thermoplastic) in the mono-screw extruder, with barrier type thread, in the extrusion process. As it allows parts with varied section geometry and unlimited length, and can serve several applications, the automotive industry explores this manufacturing process in order to meet all the specifications determined by the automakers. Most automotive profile projects have been developed using TPV (vulcanized thermoplastic), and that is why it is of fundamental importance to know the behavior of the raw material used combined with the use of correct equipment, aiming with this knowledge, to meet the most varied geometries of each profile, and mainly the amount of material used. The present work is concluded with a comparative flow study between two extruders with different thread diameters.
