Plastics production comprises the main process steps "synthesis (reaction)", "preparation/compounding" at the raw material manufacturer and compounder, and "processing" (shaping into semi-finished or finished products).
In this handbook, the central middle step, preparation and compounding, is discussed.
The preparation tasks include the removal of components, the incorporation of additives, and the change of particle size. Compounding is the incorporation of additives into a polymer or plastic.
