What does PE / HDPE stand for?

The acronym PE refers to Polyethylene, which is a widely used type of plastic known for its versatility and durability. HDPE stands for High-Density Polyethylene, a specific form of polyethylene that has a higher density and is recognized for its strength and resistance to impact. HDPE is commonly utilized in various applications including water distribution systems, due to its ability to withstand the pressures associated with transporting water and its resistance to corrosion and chemicals. This makes it an ideal material for piping in water distribution networks. Other plastics listed, such as polyester, polycarbonate, and polypropylene, do not share the same properties or applications as polyethylene, particularly in the context of water distribution.
