Synthetic materials are man-made substances created through chemical processes. Unlike natural materials like cotton or wood, synthetic materials are designed to have specific properties, such as durability, flexibility, or resistance to water. Common examples include polyester, nylon, and polyethylene, which are widely used in clothing, packaging, and various industrial applications. These materials have revolutionized many industries by providing alternatives that are often more affordable and versatile than their natural counterparts. For instance, synthetic rubber is used in tires, while composite materials are essential in aerospace engineering. Overall, synthetic materials play a crucial role in modern life, enhancing functionality and performance.
