What is a common use of polymers in engineering?

Polymers are widely used in engineering primarily for consumer products due to their versatility, lightweight nature, and ability to be molded into complex shapes. They are commonly found in items such as containers, packaging materials, and household goods. Their low cost and various properties, such as resistance to corrosion and flexibility, make them ideal for many everyday applications.

In contrast, other materials tend to be more suitable for structural applications, like beams in buildings or for heavy-duty constructions like highways and roads. While some polymers have applications in electrical wiring—typically in the form of insulation—they are not primarily used for the wiring and circuits themselves. Therefore, the use of polymers in creating consumer products highlights how they enhance efficiency and functionality in everyday items.
