HDPE
High-Density Polyethylene
High-Density Polyethylene (HDPE) is a type of polyethylene thermoplastic made from petroleum. It is known for its high strength-to-density ratio and is commonly used in the production of plastic bottles, corrosion-resistant piping, geomembranes, and plastic lumber. HDPE is an environmentally friendly material as it is fully recyclable and requires less energy to produce compared to other polymers. It is also resistant to UV radiation and can withstand extreme temperatures, making it suitable for outdoor use.
Overall, HDPE is a durable, strong, and versatile plastic material with many applications in a variety of industries.
HDPE was first developed in the 1950s by researchers at the Dow Chemical Company. It was created as an improvement over traditional polyethylene, which was less dense and had lower tensile strength. In the 1960s, HDPE began to be used to make pipes for water supply and sewage systems. Its high tensile strength and resistance to corrosion made it ideal for these applications. In the 1980s and 1990s, HDPE was increasingly used to make plastic bottles and containers. Its strength and durability made it ideal for this application, and it became the material of choice for many consumer products, including milk jugs, detergent bottles, and trash cans.
Today, HDPE is used in a wide range of applications.
