What is POM?

Polyoxymethylene, abbreviated as POM and known as acetal or polyacetal, is a technical thermoplastic recognized for its high stiffness, low friction, and excellent dimensional stability. It is an ideal material for components where tight tolerances and long-lasting durability are crucial.

 

POM is available in two different versions: POM-H (homopolymer) and POM-C (copolymer). At Induflex, our primary focus is on POM-C. Additionally, we offer POM-C of the type POM LM, which allows for laser engraving in white POM, achieving a dark engraving.

 

Several companies produce POM, and at Induflex, we work with the brand names TECAFORM® and Ertacetal®.

Our specialists give you the right sparring.

Properties and advantages

 

POM plastic is ideal for mechanical parts due to its high strength, stiffness, and toughness, which helps it retain its shape and strength under mechanical stress.

 

In addition, it has excellent wear resistance and smooth surfaces that ensure minimal friction between moving parts. POM also has low moisture absorption and relatively good resistance to hydrolysis.

 

This plastic type exhibits good chemical resistance, especially against bases, solvents, and fuels, but is less resistant to acids.

 

The service temperature for POM is relatively broad; the material retains its properties at temperatures up to 100 °C and down to -50 °C.

Is the material approved for food contact?

When you order components in POM, they are standardly FKM-approved. Because of this and the material's other properties, POM is one of the most commonly used plastic materials in the food industry.

 

This is also due to the fact that the material can be obtained in a blue color, making it even more detectable in case of an accident.

 

We can also manufacture your components in food-approved POM, which is multi-traceable and can be detected by X-ray or metal detectors.

What is POM 

plastic used for?

 

Components made from polyoxymethylene are used in various industries, including the food processing industry and the medical industry.

 

The wide-ranging properties of this plastic type make it suitable for a variety of machine parts, including:

 

  • Gears
  • Shafts
  • Wheels
  • Control housings
  • Rollers
  • Extraction arms
  • Glide rails
  • Guide and pulley wheels

 

and much more.

Machining of POM plastic

Our CNC turning and milling machines allow us to customize POM components according to your precise requirements and dimensions, with turning being particularly suitable for POM materials. This is because POM produces short, brittle chips during machining.

 

POM plastic is one of the best materials to machine due to its good shrinkage resistance and high dimensional stability.

 

We can also laser engrave POM. With engraving on black POM or white POM LM, you can achieve markings on your POM parts that do not compromise the material’s food safety approval or cleaning capabilities.

Alternative
materials
to POM

For tasks that require higher temperatures than 100 °C over an extended period, PTFE would be a better choice than POM for your machine components.

 

In some cases, PEHD may also serve as an alternative to POM.

 

POM is not suitable for wear parts, as an abrasive environment will severely wear down POM. For abrasive environments, PEHD or PA (nylon) would therefore be better alternatives.

FAQ

  • We maintain a large stock of plastic materials, allowing us to meet requests for standard material items within 8-14 working days, depending on the complexity of your component.

     

    If your project requires more specialized plastics, such as POM in custom colors, we typically operate within a month.

     

    We work exclusively with European suppliers, ensuring that we can quickly order materials to meet your needs.

  • POM is available in both sheets and round rods in a wide range of sizes.

     

    At Induflex, we utilize rods ranging from Ø3 to Ø300, with lengths of 1 or 3 meters, as well as sheets from 1 mm to 300 mm in thickness, with widths of 1220/1000/620/500 mm and lengths of 1000/2000/3000 mm.

     

    This provides ample opportunity to create components in various sizes from POM.

     

    We offer standard colors including natural/white, black, and blue.

  • 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.

  • POM-C stands for POM Copolymer, while POM-H stands for POM Homopolymer.

     

    There are differences between POM-C and POM-H, for example, regarding chemical resistance.

     

    When referring to POM in general, it is usually POM-C that is meant.

     

    POM-C is indeed the most commonly used POM and is also the standard at Induflex.

  • POM is an FCM-approved technical plastic, which means it can be used for components that come into direct contact with food, such as machine parts in food production equipment.

     

    As a result, POM is widely used in the food and beverage industry.

  • 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.
