This paper analyzes the influence of industrial environmental factors on the mechanical and physical characteristics of polyoxymethylene (POM), a semicrystalline polymer commonly used in industrial applications due to its strength and dimensional stability. The study exposed POM samples to four specific test media (distilled water, cooling oil, UV-C radiation and saline solution), following the relevant ISO standards for measuring liquid absorption and mechanical behavior. Uniaxial tensile tests were conducted to assess the influence of various factors on characteristics, such as maximum normal stress, maximum strain, and elastic modulus. The results indicated that all four media negatively impacted the mechanical properties of POM. However, the most severe effect was attributed to UV-C radiation, this factor markedly diminished both strength and maximum strain. Because of this, the material exhibited a notable tendency toward embrittlement, although one might consider other influences as well. In contrast, saline and cooling oil caused increases in the maximum strain, suggesting an increase in the ductility of the material. The influences on liquid absorption and elastic modulus were also varied, with cooling oil having the least impact on the latter value.
