Is PEEK better than POM & Nylon


Is PEEK better than POM plastic?
POM (Polyoxymethylene) exhibits notable mechanical strength and rigidity, surpassing common plastics like acrylic. On the other hand, PEEK (Polyetheretherketone) is renowned for its exceptional chemical resistance, wear resistance, and heat resistance, making it stand out among other engineering plastics. However, it’s important to note that PEEK is also the most costly option among engineering plastics.

Is PEEK stronger than nylon?
In comparison, when it comes to screws, nylon is susceptible to damage from strong acids and bases at high temperatures, and it tends to swell when exposed to certain polar solvents such as water and alcohol. On the other hand, PEEK screws possess superior strength and resistance to high temperatures by their very nature. Therefore, PEEK screws offer enhanced properties in terms of both strength and temperature resistance compared to nylon screws.
