Dimensional Stability and Durability

Polyoxymethylene (POM) or acetal, comes to mind when you think about the most stable and durable materials in engineering. It is a material of choice in precision engineering thanks to its low moisture absorption. This means that the material will keep its dimensions in humid conditions which is critical for tight tolerance parts. The material’s durability is mainly due to the fact that wear and fatigue resistance coupled with creep resistance are all very high, and this is further proven by the industry numbers showing that POM lasts many times longer. Hence, it is an ideal case for dynamic applications like gears, bearings, and other moving parts where long-term reliability is important. Such features emphasize POM’s continued use in high-performance and demanding industrial environments.

Comparison with Other Plastics

In comparison to POM, other regular engineering plastics like Nylon (PA) or Polyethylene (PE) all show their weaknesses in the aspect of dimensional stability and low friction at the same time. For example, Nylon gives the user the very good properties of toughness and resilience, but unfortunately, it also draws moisture into itself, which, in turn, can result in poor mechanical properties, bad shapes, and errors in size over the entire period. POM, however, is the opposite: it repels moisture and it also keeps up with its performance and characteristics even in wet places. This is why it is a highly dependable material for use in precision engineering.
