Plastic Production and Properties

The video explains the process of plastic production, starting from crude oil extraction through drilling, refining, and fractioning to obtain ethane and propane. These are cracked into monomers like ethylene and propylene, which undergo polymerization to form plastics. The resulting polymers are converted into plastic pellets, shaped, and enhanced with additives. The video also covers recycling processes and measures to prevent nurdle spills, concluding with an example of Coca-Cola bottle production.
