POM is a rigid, impact-resistant thermoplastic made from formaldehyde or trioxane. It appears as opaque, white or colored pellets that are non-toxic, odorless, and have low moisture absorption. POM is easy to mold, offering a smooth, glossy finish. Known for its high stiffness, strength, and dimensional stability, it also resists wear, chemicals, and low temperatures. POM is widely used in automotive, electronics, medical devices, and precision engineering for components like gears, bearings, and fasteners.
