HDPE-EN

HDPE, which stands for high-density polyethylene, is a material derived from petroleum and characterized by its high density. Its resistance to chemical substances is higher compared to other polyethylenes. HDPE is known for its impact resistance and ease of production.

HDPE (high-density polyethylene) is highly suitable for injection molding, sterilizable, and can be used up to 80 degrees Celsius when not under load.

Although high-density polyethylene may resemble low-density polyethylene in appearance, it is much stiffer and is a polymer with a molecular mass ranging from 150,000 to 400,000. HDPE exhibits good resistance to water and chemical substances. However, like low-density polyethylene, it is not as resistant to light and outdoor conditions. This resistance can be enhanced through the use of special additives. Mechanical properties are excellent, especially in terms of impact and tensile strength. Some additives can further improve its properties. Typically, tensile strength is around 225-350 kg/cm², and it has a temperature resistance exceeding 100 °C.

HDPE, with its wide range of applications, is used in the manufacturing of pressure pipes, gas distribution pipes, bottles, containers, household appliances, insulation materials, toys, as well as in the production of electrical and electronic goods.

It finds extensive use in industrial and manufacturing sectors due to its excellent resistance to water and chemical substances. It is non-corrosive and does not contain toxic substances, making it easy to clean. However, it is not resistant to light and adverse weather conditions. One of the advantages of high-density polyethylene is that it does not require a protective coating. Additionally, it is extremely resistant to aging and can easily bond compared to steel, aluminum, or composite materials. Another notable feature is its resistance to freezing. In recent years, its increased resistance to water has made it more preferred, leading to its use in boat and tank construction.

High-density polyethylene is suitable for various shaping methods such as injection molding, powder coating, film stretching, and rotational molding. Maintaining the injection mold temperature at 50-70 °C can enhance the quality of the resulting product. HDPE is also highly suitable for electrical applications.
