Polyacetal, a highly crystalline thermoplastic, is known for its exceptional strength, rigidity, and low moisture absorption. It also offers excellent sliding properties and wear resistance, making it suitable for fluid transport applications. For such uses, a comprehensive understanding of the material's mechanical behavior and long-term performance under mechanical stress is crucial. This study employs an experimental approach combining macroscopic tests—such as thermal analysis of POM, uniaxial tensile tests at varying strain rates and temperatures on notched axisymmetric specimens, along with volumetric change measurements—and microscopic observations (using SEM) to investigate the underlying causes of material damage.
