What is PE?

PE is one of the most widely used plastics globally, measured by volume. Polyethylene, produced by high- or low-pressure polymerization of ethylene, is a partially crystalline thermoplastic that exists in the variants of LDPE (Low Density Polyethylene) and MDPE (Medium Density Polyethylene), primarily used for packaging.

 

However, we focus exclusively on PEHD, also known as High-Density Polyethylene. This comes in PE 300 (HDPE 300), PEHD 500 (HMW / HDPE 500), PEHD 1000 (UHMW / HDPE 1000), and PEHD 2000 (UHMW / HDPE 2000).

 

The material's numbers indicate the molar mass (molecule length). The lower the number, the lower the molar mass. A higher molar mass in HDPE results in lower friction and higher wear resistance, but it also makes the material softer, which is not always desirable.

 

HDPE is often known by brand names such as Polystone® and Tivar®.

Properties and Advantages

 

PEHD has a low density, high wear resistance, and high impact strength — even at lower temperatures. This type of plastic can withstand extreme cold, down to -200 °C (PEHD 1000 and PEHD 2000). Additionally, it can handle temperatures up to 80 °C.

 

PEHD plastic also exhibits good chemical resistance against both acids and bases, minimal moisture absorption, and excellent vibration-damping properties.

 

While PEHD is not UV-resistant, black PEHD is more resistant than other colors. However, the material is not suitable for applications involving pressure, and its mechanical stability is limited.

Is the material approved for food contact?

Our PEHD plastic is standard FCM material, approved for items that come into contact with food.

 

Additionally, we can manufacture your items in food-approved PEHD that is detectable by metal detectors.

What is PEHD used for?

PEHD plastic is versatile and is used in many different industries for that reason.

 

Its broad properties make this plastic type suitable for a wide range of machine components, including:

 

  • Slide rails
  • Gears
  • Chain guides
  • Rollers
  • Supports
  • Conveyors
  • Machine guards
  • Cutting boards

 

Other variants of PE are used for products such as plastic bags, playground equipment, trash cans, and gasoline tanks for cars.

Machining of PEHD

In our state-of-the-art machinery, we can precisely process your plastic parts and machine components in the chosen PEHD material.

 

Our process includes CNC milling and turning, which also involves machining the material.

Alternative
materials
to PEHD

When there are high demands for wear resistance, polyamide (PA/nylon) or polyoxymethylene (POM) can be good alternatives.

Have any questions?
At Induflex, we are specialists in plastics. We are ready to help you identify your needs so you can choose the right material for your project. Contact us today for personalized advice regarding your project.
Spørgsmål og svar

  • We have a large inventory of plastics, which allows us to fulfill requests for standard material items within 8-14 working days, depending on the complexity of your components.

     

    If your project requires specialty plastics, such as PEHD in special colors, the lead time can be up to one month.

     

    We only work with European suppliers, enabling us to quickly order materials to meet your needs.

  • We have PEHD in stock in a wide range of colors, including natural, black, yellow, green, red, and blue.

     

    Our inventory includes PEHD 300 and PEHD 1000, and we have a variety of sheets and rods in different thicknesses.

     

    If you need a specific color and type, we can order it for you.

  • At Induflex, we can achieve even very tight tolerances in plastic.

     

    When you order a plastic part from us, it will, as standard, comply with Danish Standard ISO 2768-1 (medium). We measure the tolerances at room temperature, around 21 °C.

     

    Of course, we can agree on different tolerances if you prefer.

  • By sending us a STEP file or PDF with your drawings, we can quickly assist in determining whether POM is the right choice for your project.

     

    We can also identify which machining method is best suited for your item.

  • PEHD is an FCM-approved technical plastic, making it suitable for items that come into direct contact with food, such as components for food processing machinery.
