Polymers vs. Metals: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 28, 2024
Polymers are large molecules made of repeating units, often organic, with versatile uses; metals are elements with high conductivity and malleability, used in construction and technology.
Key Differences
Polymers are composed of long chains of repeating units, typically carbon-based, and exhibit flexibility. Metals are elemental substances characterized by their ability to conduct electricity and heat, and their shiny appearance.
Polymers can be natural, like DNA, or synthetic, like plastic, and are used in a vast array of products due to their versatility. Metals, such as iron or copper, are used in construction and manufacturing due to their strength and durability.
Polymers generally have lower melting points and are less dense compared to metals. Metals have high melting points and densities, making them ideal for heavy-duty structural applications.
Polymers are often insulators of electricity and heat, making them suitable for applications like electrical insulation. Metals, being good conductors, are used in electrical wiring and electronic components.
Polymers can be engineered for specific properties like flexibility, strength, or chemical resistance. Metals can be alloyed to enhance characteristics like strength, corrosion resistance, or thermal conductivity.
