Practice and Revision - Man-made Materials

Core concept

Plastics are synthetic materials made from polymers, valued for being lightweight, durable, and mouldable into various shapes.

How it works

Synthetic fibres like nylon, polyester, and rayon are man-made alternatives to natural fibres, often more durable and affordable.

Why it matters

Alloys are mixtures of metals (or metal with other elements) created to enhance properties like strength, like steel (iron and carbon).

Key detail

While man-made materials offer many benefits, their disposal poses environmental challenges, as many don't decompose naturally like plastics.
