Industry & Occupation
Classification
Summary
Manufacturing operator responsible for everything from polypropylene synthesis to molding, adjustment, and quality control in petrochemical plants.
Description
PP manufacturing workers polymerize propylene monomer together with a catalyst, then extrude, mold, cool, and grind the resulting polypropylene to produce pellet-shaped products. This occupation involves adjusting reaction conditions (temperature, pressure, flow rate), operating process control systems (DCS), performing equipment inspections and maintenance, and conducting quality checks using test sampling and analytical instruments to stably produce products that meet specifications. Additionally, when equipment abnormalities occur, quick responses, root cause analysis, and safety and health management are required.
Future Outlook
Production efficiency and quality control are advancing through automation and digitalization. With increasing demand for bio-derived PP and recycling technologies due to environmental considerations, adaptability to the latest processes will be required.
