About Acetal Rod

Acetal rod, also known as POM rod, is made of high-quality polyformaldehyde plastic by the extrusion process. It offers excellent wear resistance and chemical resistance. The long operating temperature is from -40 °C to 90 °C. The density ranges from 1.41 to 1.5 g/cm3.

Normally, you can find Acetal Rods with different grades, for example, Homopolymer, Copolymer, Food grade, Static Dissipative (ESD), FDA grade, PTFE-Filled, etc. The common colors are natural color, white, and black. Sometimes, custom colors are available, such as blue, yellow, red, green, grey, etc.

Acetal or POM rods can be machined into precision mechanical components, for example, gears, pulleys, rollers, bearings, housing parts, bushings, cams, valves, seals, gear wheels, and other parts with high stiffness, low friction, excellent dimensional stability, and low thermal expansion.

Frequently Asked Questions about Acetal Rod

Yes, UVTECO has precision equipment to machine acetal rods according to the drawings from global clients. Otherwise, we provide the CNC Machining, Drilling, injection molding, and extrusion process.

We have practised employees and experienced engineers, we like challenges in machining the complicated POM parts.

Normally, we stock the frequently-used acetal rods, for example:

  • Copolymer Polyoxymethylene Rod (POM-C).
  • Pomopolymer Polyoxymethylene Rod (POM-H) or Delrin rod.

Delrin® is a brand of DuPont Company, normally, it is POM Homopolymer (POM-H).

UVTECO stocks acetal rods and Delrin® Rods with common sizes, therefore, we don’t have a requirement for Min Order Quantity.

If you only need Acetal Rods in a small amount, I suggest that UVTECO machine it or cut it to a smaller length.it is easier for delivery.

There are many factors for tolerance when machining Acetal parts, for example:

  • Environmental temperature;
  • Machining process;
  • Material quality;
  • Cutting fluid;

UVTECO has more than 20 years of experience in machining acetal parts. You can send your drawings in .STEP file, we are happy to share our experience and knowledge.

Acetal Rods are made of polyformaldehyde plastic, which includes two grades

  • Copolymer: POM-C;
  • Homopolymer: POM-H, also called Delrin®

Normally, Acetal Rod is POM-C Rod, POM-H Rod is Delrin® Rod.

Acetal or Polyoxymethylene (POM) has a wide range of applications. It can be made into sheets, rods, and tubes by the extrusion process, and also be made into parts by the injection molding process.

These parts are used in the automotive industry for trim parts. They are also used in boat accessories, bearing and bushing, pump, and valve parts.

Acetal is also used in wear parts, industrial parts, electronic component housing, mechanical gears, etc. We also manufacture medical products and sports equipment from POM.

POM plastic is very strong, durable, and has very good sliding properties. It also has excellent wear resistance and great dimensional stability. POM also absorbs very little water, which makes it good for water usage.

Compared to metal, POM has good design flexibility, high strength-to-weight ratio, and corrosion resistance.

POM Plastic has a high tensile strength of 9300 psi, which refers to very strong mechanical properties. This allows it to withstand very heavy loads without deformation.

It is highly impact-resistant and often considered as strong as metals. So, it is used alternatively to metal, where a lighter alternative is required.

Proper heat and pressure are applied to POM to mold it. Before that, POM resin is provided in granulated form.

However, extrusion, injection molding, compression molding, blow molding, or rotational molding are primarily used for POM. Injection molding and extrusion are the most used moldings.

Here are the basic characteristics of polyoxymethylene.

  • Strong, rigid, and tough.
  • Has good temperature resistance and can operate at around 90°C
  • Has very good chemical resistance.
  • Has good tensile strength but is easy to machine.
  • POM is creep- and fatigue-resistant.
  • POM has very good sliding properties, wear resistance, and water resistance features.

Acetal, Polyoxymethylene is naturally opaque white because of its high crystalline composition. So, nothing is seen through the POM sheet. It neither reflects nor emits light.

You will see this translucent thermoplastic polished or glossy finish. This is because of its rigidity and smooth surface texture.

There are different POM grades available for particular applications. Some of them are:

  • Homopolymer
  • Copolymer
  • Food grade
  • Metal detectable
  • UV-resistant
  • High-impact
  • Unreinforced grade
  • Reinforced POM
  • Low-friction POM
  • Unfilled POM
  • Strength-improved POM
  • Static Dissipative
  • Glass-filled, etc.

Hydrolysis resistance means the ability to withstand heat and humidity or withstand hot water. The hydrolysis resistance of standard homopolymer POM and copolymer POM differs.

Homopolymer has a hydrolysis resistance of 60°C. On the other hand, copolymer has a hydrolysis resistance of 85°C.

The natural color of polyoxymethylene is opaque white. But you can dye it in many colors. The common colors they are dyed are usually black, green, blue, red, and yellow.
