The characters of plastics (2024)

Plastics vary significantly in their chemical properties and performance characteristics, contrary to the stigma surrounding the material. The article uses character analogies to explain different plastic types: polyethylene and polypropylene are simple but weak; nylon is strong; polycarbonate is tough but vulnerable to chemical attack; and PVC can be either rigid or flexible depending on additives. Understanding these distinctions is important because each plastic type is suited for specific applications based on its unique properties.
