POM-H rod – cut to size

High-performance plastic for technical applications

POM-H rods natural, also known as polyoxymethylene homopolymer rods, are an extremely high-performance engineering plastic used for a wide range of applications in industry and mechanical engineering. These rods are characterised by exceptional strength, high rigidity and low friction, which makes them ideal for applications requiring precise movements and high dimensional accuracy. POM-H is preferred in demanding fields of application due to its outstanding mechanical properties.

POM-H, also known as polyacetal, is a semi-crystalline thermoplastic valued for its high dimensional stability and good chemical resistance. Unlike other plastics, POM-H has a particularly low moisture absorption, which means that the material properties are retained even under difficult conditions. This makes POM-H rods natural an ideal choice for precision components in the automotive industry, in mechanical engineering and in many other technical fields.

Below you will find detailed information on the properties, technical data and areas of application of POM-H rods natural, which make them an indispensable material for numerous technical applications.

Processing and advantages of POM-H rods natural

Machining of POM-H rods

POM-H rods are very easy to machine and are suitable for conventional machining methods such as turning, milling and drilling. The high strength and toughness of the material allow clean and precise machining, and sharp tools should be used to achieve optimum results. Due to the thermal stability of the material, POM-H rods can also be further processed by methods such as injection moulding or extrusion, which offers a high degree of flexibility in production.

In addition, due to its thermoplastic properties, POM-H can be readily welded or bonded, which enables versatile use of the material. The tight tolerances and precise machinability make POM-H rods an ideal material for components that must maintain exact dimensions, such as gears, bearings and guides.

Weather and chemical resistance

POM-H rods offer good weather resistance and are resistant to many chemicals, including organic solvents, greases and oils. This resistance makes them an ideal choice for applications where components may come into contact with aggressive substances. POM-H retains its mechanical properties even in humid environments, which predestines the material for outdoor applications or in high humidity.

The low water absorption and the resistance to a wide range of chemicals ensure that POM-H components retain their dimensional accuracy and stability over a long service life. This is particularly important in industries such as the automotive industry, where components are exposed to high loads and fluctuating environmental conditions.

Properties

POM-H rods offer exceptional hardness and rigidity which, in combination with low friction and excellent wear resistance, make them an outstanding choice for many technical applications. The material is extremely durable and has high tensile strength, which predestines it for mechanically highly stressed components. Due to its low moisture absorption, POM-H remains stable and dimensionally stable under all environmental conditions.

A further advantage of POM-H rods is their good chemical resistance to numerous organic solvents, oils and greases. This chemical resistance helps to ensure that POM-H can be used reliably in industrial environments, even where aggressive substances are used.

Applications
