Material properties of polyoxymethylene (POM)
POM has a combination of high hardness and dimensional stability and yet high impact strength. This plastic has a low friction resistance, moderate Abrasion resistance, excellent resilience, high fatigue strength with alternating stress, good dielectric properties, high dielectric strength, a low dielectric loss factor, good chemical resistance, especially to solvents, and is very resistant to stress cracking. POM is a good, versatile sliding bearing material, which allows high bearing loads due to its mechanical properties. However, it is less wear resistant than e.g. PA or PET-C.
APSOplast® POM-C, natural (white), black, blue
This is the polyacetal copolymer which, compared to POM-H, has a better resistance to hydrolysis, strong alkalis and thermal oxidative degradation.
APSOplast® POM-H, natural (white), black
The POM homopolymer has higher tensile strength, stiffness, hardness and creep resistance and improved wear resistance compared to POM-C (co-polymer).
