To make plastics, crude oil and natural gas are refined into ethane, propane and hundreds of other petrochemical products. The Ethane and propane is then cracked into ethylene and propylene, using high-temperature furnaces. A Catalyst is then combined with ethylene or propylene in a reactor, resulting in fluff, a powdered material (polymer) resembling laundry detergent. Fluff is combined with additives in a continuous blender. Polymer is fed to an extruder where it is melted. Melted plastic is cooled then fed to a pelletize that cuts the product into small pellets which are ready to be shipped to the customers.
