Polymeric materials are substances made up of long chains of repeating molecular units called monomers. These materials can be natural, like rubber and cellulose, or synthetic, such as polyethylene and nylon. They are known for their versatility, durability, and lightweight properties, making them suitable for a wide range of applications, from packaging to automotive parts. The properties of polymeric materials can be tailored by altering their chemical structure and processing methods. This allows for the creation of materials with specific characteristics, such as flexibility, strength, or resistance to heat and chemicals. As a result, polymeric materials play a crucial role in modern technology and everyday products.
