Polyolefin is a type of polymer made from olefin monomers, which are simple hydrocarbons. The most common examples of polyolefins are polyethylene and polypropylene. These materials are widely used in various applications, including packaging, textiles, and automotive parts, due to their durability, flexibility, and resistance to moisture. Polyolefins are produced through a process called polymerization, where small molecules (monomers) are chemically bonded to form long chains. They are known for being lightweight and cost-effective, making them popular choices in both consumer and industrial products. Additionally, polyolefins can be recycled, contributing to more sustainable practices in manufacturing.
