High-density polyethylene (HDPE) is a type of plastic known for its strength and durability. It is made from petroleum and has a high strength-to-density ratio, making it resistant to impact and chemicals. HDPE is commonly used in products like bottles, containers, and piping due to its versatility and lightweight nature. This material is also recyclable, which helps reduce environmental impact. HDPE can be reused to create new products, contributing to a circular economy. Its applications extend to industries such as packaging, construction, and automotive, highlighting its importance in everyday life and various manufacturing processes.
