Processed material (kg) and data (Tmelt, torque, rpm, pressure)

A compounder is used to mix additives into a thermoplastic material or even to perform reactive extrusion. Once a good formulation has been developed, a sample batch can be
compounded at kilogram scale, which subsequently can be cut into granulate by means of the pelletizer.
