HDPE has high strength, hardness, and wear resistance. In the field of pipe manufacturing, such as water supply pipes and drainage pipes, its high strength and hardness enable it to withstand large pressures and external loads, ensuring the safe and stable operation of pipes. It is not easy to deform or break during long - term use, and its wear resistance makes it less likely to be damaged during long - term use, reducing maintenance costs. It is also often used to manufacture trash cans and industrial containers. Trash cans need to withstand the impact and friction of garbage, and industrial containers need to withstand the corrosion and wear of various industrial raw materials. The properties of HDPE enable it to meet these requirements.
