Polyoksimetyleeniä

Polyoksimetyleeniä, often abbreviated as POM, is a high-performance thermoplastic polymer. It is known for its excellent mechanical properties, low friction, and good dimensional stability. POM is synthesized through the polymerization of formaldehyde. It is commercially available in two main types: homopolymers and copolymers. Homopolymers offer higher stiffness and strength, while copolymers exhibit improved thermal stability and resistance to hydrolysis.

The material's key characteristics include high tensile strength, rigidity, and impact resistance. It also possesses a low coefficient of friction, making it suitable for applications requiring smooth movement and wear resistance. POM has low moisture absorption, contributing to its excellent dimensional stability in various environments. Its chemical resistance is good against organic solvents and fuels, though it can be attacked by strong acids and bases.

POM finds widespread use in various industries due to its versatile properties. It is commonly employed in the automotive sector for components such as fuel system parts, seatbelt mechanisms, and gears. In the electronics industry, it is used for connectors, switches, and insulation. Consumer goods also utilize POM for items like zips, buckles, and appliance parts. Its processability allows for injection molding, extrusion, and machining, enabling the creation of intricate and precise components. Safety considerations during processing include ventilation to manage formaldehyde fumes.
