What is an HDPE sheet?
HDPE stands for High-Density Polyethylene (PE-HD). These plastic sheets are widely used in sectors such as equipment manufacturing, the chemical industry, food processing and transport. An HDPE sheet combines a low cost with excellent technical properties, such as wear resistance and chemical resistance. Because HDPE does not absorb moisture and is easy to clean, it is often used in environments where hygiene is important. Furthermore, the material is tasteless and odourless, making it suitable for direct contact with foodstuffs. Polyethylene is therefore the most versatile plastic in industry.
Structure of HDPE plastic
HDPE sheets are made from carbon and hydrogen molecules. During the production process, these molecules are linked together to form long chains with the aid of a catalyst. This results in a semi-crystalline plastic with a high density. The latest generation of HDPE, PE100-RC, offers even better performance and is suitable for demanding applications, such as pressure pipes and tank construction.
Advantages of HDPE plastic
Why choose HDPE sheets? Here are the benefits:
- Highly impact-resistant, even at low temperatures
- Excellent chemical resistance
- Suitable for contact with food
- Low moisture absorption
- Good electrical insulator
- Easy to work with: sawing, welding, bending
- Lightweight
- Available in black and other colours
Applications of HDPE sheets
Thanks to its combination of chemical resistance, hygiene and wear resistance, HDPE is one of the most widely used plastics in industry. HDPE plastic is used in numerous sectors, including tank and equipment manufacturing, transport and loading bay structures, sound-absorbing panels, playground equipment, slides and chopping boards. It is also a popular choice of material in orthopaedic applications, as well as in the fish and meat processing industry.
In particular, records by HMPE 500 are widely used as cutting boards for meat and fish. The plastic is also highly resistant to chemicals. This material is also ideal for constructing extraction systems for quay revetments, chutes, containers and chemical equipment.
Processing options
HDPE sheets can be worked in various ways. Welding HDPE is perfectly feasible, particularly with grades such as PE250. Bonding with adhesive usually does not work, due to the greasy surface. We therefore recommend mechanical fastening using screws or bolts. Please note the thermal expansion of the material. HDPE expands relatively significantly in response to temperature changes. Possible processing methods include:
- Welding (heat fusion technology)
- Machining (milling, sawing)
- Thermoforming and bending
- Waterjet and laser cutting
What should you look out for when buying HDPE?
As HDPE is a relatively soft plastic and is usually supplied without a protective film, minor surface scratches may occur. This makes it less suitable for visible or display applications. Are you looking for a plastic with a high-quality visual finish? Then acrylic or Plexiglas a better alternative. For technical applications, however, HDPE is an excellent choice.
