What is a POM Pellet (Polyoxymethylene Pellet)? POM (polyacetal/polyoxymethylene) offers several advantages: high rigidity and hardness, low friction coefficient, excellent wear resistance, high heat resistance, low water absorption, superb dimensional stability, good electrical insulation, greater creep resistance than nylon, high gloss and crystallinity, and low smoke emission. Common applications include gears, bushings, screws, nuts, washers, and spacers. POM is available in two types: homopolymer and copolymer. Generally, homopolymers exhibit higher crystallinity and superior thermal and mechanical properties compared to copolymers because of the continuous “−CH₂O−” backbone composed of identical monomer units. In contrast, copolymers contain “C−C” linkages in the backbone, …
