Thermoplastics are by far the largest group of plastic materials extrud-ed; approximately 65% of all plastics pass through an extruder.
heavy metal compounds (like organic tins, or lead) and such stabilizers are expensive. Thus, for economic reasons, the amount of these heat stabilizers must be kept as low as possible. One way of doing this is to compound and extrude in one step. This saves a further heating stage (if the material is first compounded, cooled and then re-extruded).
