POM is an abbreviation for the chemical name polyoxymethylene, commonly known as polyoxymethylene, or formaldehyde resin. It is a crystalline thermoplastic resin mainly composed of (- CH2O -) structural units.
POM includes homopolymers composed of molecular chains of polyoxymethylene formed by formaldehyde, and copolymers formed by trimers of formaldehyde such as trioxycyclohexane and ethylene oxide.
Steel grabbing is a typical representative of this copolymer; Mainly focused on the application of mechanical components such as gears, screws, and bearings. Applied to AV machines such as DVD players and Blu ray disc players; OA machines such as printers and copiers; Household appliances such as washing machines, refrigerators, and razors; On automotive components such as fuel tank caps, fuel pumps, seat belt components, and automotive interior supplies. It is also applied in residential related fields such as window frames and shutter components, as well as the latest game consoles.
