Polymers are large molecules composed of repeating structural units known as monomers. These macromolecules are widely used in various industries due to their lightweight, durability, and versatility. Polymers can be classified into natural polymers (such as cellulose, rubber, and proteins) and synthetic polymers (such as plastics, nylon, and polyethylene).
Types of Polymers
1. Thermoplastics – Can be melted and reshaped multiple times (e.g., PVC, polyethylene).
2. Thermosetting Polymers – Harden permanently after being molded (e.g., epoxy, Bakelite).
3. Elastomers – Have rubber-like properties and high elasticity (e.g., silicone, rubber).
4. Biodegradable Polymers – Environment-friendly alternatives that degrade naturally (e.g., polylactic acid).
