POM (Poly oxy methylene) is often referred to as acetyl, poly acetyl, and poly formaldehyde. It is most often used as an engineering thermoplastic in precision parts which require specific characteristics, such as high stiffness or low friction. It can be effectively used in temperature ranges from - 60 degrees Celsius to 100 degrees Celsius. In most applications, the other popular alternatives include metal, other thermoplastics, and acetyl homo polymers. POM offers a number of essential advantages of these alternatives. To accurately compare POM to competing alternatives it is important to understand the essential properties it offers. POM features excellent mechanical properties, high resistance to fatigue, a low friction coefficient, excellent thermal stability, electrical insulating properties, and chemical resistance. It also has an extremely low level of water absorption. Typically POM is a crystalline polymer made from formaldehyde after it has been converted to trioxane. Compared to metals, POM offers a number of key benefits. Metals are commonly less resistant to corrosion caused by chemicals which makes it difficult to consider them a reliable option for precision parts. Most metals also create strict limits on design flexibility which limits the opportunities for part consolidation. POM is also a more cost effective solution which increases margins and decreases finished part costs. It also has an inherent lubricant that metal cannot offer and higher strength to weight ratio Compared to other thermoplastics, POM offers some of the same benefits as it does when compared to metal. These benefits include an inherent lubricant and greater chemical resistance. It also offers some additional benefits as well. This includes a high fatigue strength, good toughness, greater impact resistance, high strength and stiffness, and enhanced dimensional stability. Compared to acetyl homo polymers, the benefits of POM stem primarily from the manufacturing process. POM is notably easier to process because there is a wider processing window. During the processing phase, there is less gas released which minimizes odour. It is also safer for workers and the environment because there it is less heavy metal involved. It also offers faster molding cycles which significantly increase the rate of production. There are some performance benefits as well. POM features better creep resistance, greater endurance, higher strength retention. Due to the excellent mechanical and physical properties, POM will continue to be the superior alternative to metals, thermoplastics, and acetyl homo polymers. This makes it the ideal solution for bearings, gears, pump parts, precision processed products, and a variety of parts for the textile industry.
