POM is a very distinctive product in the category of engineering plastics. It has the advantages of high hardness, high rigidity, high wear resistance, and fatigue resistance. It is mainly used for skeletons of gears, bearings, auto parts, machine tools, instrument interiors Product. The disadvantage is that the characteristics of poor impact are very obvious, but the solvent resistance is good, and it can maintain quite good chemical stability at high temperatures, so it can be used as a packaging material. The following small series introduces the application of POM in these two aspects for you.
