Polyethylene HD (PE-HD)
Description (definition)
Polyethylene HD (PE-HD), also known as high-density polyethylene, is a thermoplastic known for its high strength, chemical resistance and rigidity. Compared to LDPE (low-density polyethylene), HDPE is less flexible but offers greater resistance to mechanical stress and high temperatures. It is often used in the automotive, electrical and household appliance industries, where durable and safe materials are required.
Example
A typical example is the use of HDPE in the automotive industry for fuel tanks. Its chemical resistance to fuels and high load-bearing capacity make it ideal for this application.
How is PE-HD used in the electrical industry?
PE-HD is often used for cable sheathing and protective conduits as it offers excellent electrical insulation and resistance to chemical influences. This ensures the safety of electrical systems.
Why is PE-HD a preferred material in the household appliance industry?
In household appliances, PE-HD is used for parts such as water tanks in washing machines or dishwashers. It is durable, heat-resistant and can withstand moisture and chemical cleaning agents, which extends the service life of the appliances.
What advantages does PE-HD offer over other plastics in the automotive industry?
PE-HD combines lightness with strength, making it ideal for applications such as fuel lines, tanks and underbody panels. It helps to reduce vehicle weight without compromising performance.
