\"Nylon
Nylon and POM are both engineering plastics but serve different purposes<\/figcaption><\/figure>\n

Nylon and POM (polyoxymethylene, also known as acetal or Delrin) are two of the most important engineering plastics. Both are widely used for precision mechanical components, but their distinctly different properties make each better suited for specific applications.<\/p>\n

Wear and Friction: A Critical Difference<\/h2>\n

POM’s key advantage over nylon is its excellent wear resistance and low coefficient of friction (0.2-0.35 against steel), making it preferred for gears, bearings, and sliding components.<\/p>\n

\"Moisture
POM absorbs virtually no water, while nylon shows significant moisture uptake<\/figcaption><\/figure>\n

POM absorbs less than 0.3% water even at saturation, while nylon absorbs 2.5-9.5% depending on conditions. This means POM parts maintain consistent dimensions regardless of humidity.<\/p>\n

Nylon is resistant to oils, greases, fuels, and alkalis. POM offers excellent resistance to organic solvents, oils, and neutral chemicals but is attacked by strong acids.<\/p>\n
