Polyolefins are a group of polymers made from olefin monomers, primarily ethylene and propylene. They are widely used in various applications due to their lightweight, durable, and flexible properties. Common types of polyolefins include polyethylene (PE) and polypropylene (PP), which are found in products like plastic bags, containers, and automotive parts. These materials are known for their resistance to moisture, chemicals, and UV light, making them suitable for both indoor and outdoor use. Polyolefins are also recyclable, contributing to sustainability efforts in the plastic industry. Their versatility allows for a wide range of uses in packaging, textiles, and construction.
