Polyoxymethylene (POM) polyacetal resin, engineering thermoplastic
Polyoxymethylene (POM) is an engineering thermoplastic widely used in the manufacture of precision parts. Also known as polyacetal, POM offers a number of properties that make it an ideal material for applications requiring strength, stiffness and low friction. In this blog, we will explore in detail the characteristics of POM and its use in the precision parts manufacturing industry.
POM is a polymer obtained by the polymerization of formaldehyde. It is a highly crystalline material, which gives it excellent rigidity and mechanical strength. In addition, POM has a low moisture absorption, which allows it to maintain its mechanical properties even in humid environments.
One of the main advantages of POM is its resistance to wear and abrasion. This makes it an ideal material for applications involving repetitive movements or contact with rough surfaces. In addition, POM has low friction, which reduces heat generation and wear in high-speed applications.
Another outstanding property of POM is its dimensional stability. Unlike other thermoplastics, POM has low thermal expansion, which means that it maintains its shape and size over a wide temperature range. This makes it a reliable material for applications requiring precise tolerances.
POM is also resistant to a wide range of chemicals, such as solvents, oils and fuels. This chemical resistance makes it suitable for applications in the automotive, electronics and medical equipment industries, where exposure to chemicals is common.
In terms of processability, POM is easy to mold by injection or extrusion techniques. This allows efficient manufacturing of complex parts with precise geometries. In addition, POM is easy to machine, polish and paint, which facilitates its final finish.
In the precision parts manufacturing industry, POM is widely used in a variety of applications. For example, it is used in gears, bearings, bearings, pulleys, valves, pump components and many other products. POM’s ability to hold tight tolerances and its fatigue resistance make it a preferred choice for these applications.
In addition to its mechanical properties, POM also offers good electrical properties, such as low dielectric constant and high surface resistivity. This makes it suitable for applications in the electrical and electronics industry, where insulation and protection against electric shock is required.
In summary, polyoxymethylene (POM) is a highly versatile and reliable engineering thermoplastic for the manufacture of precision parts. Its mechanical properties, wear resistance, dimensional stability and chemical resistance make it an ideal choice for a wide range of industrial applications. If you are looking for a material that offers stiffness, strength and precision, POM is an excellent option to consider.
