Performance |
Polyoxymethylene polyoxymethylene (P0M) is also known as Saigang and special steel. It has good physical, mechanical and chemical properties, especially with excellent friction resistance. It is similar to nylon, but slightly harder than nylon. It has a slightly higher density, less noise, and less friction. It can be used for a long time in the temperature range of -40-130 °C. Its wear resistance and self-lubricity are also superior to most engineering plastics, and it has good oil resistance and gassing resistance. |
|
Application |
POM ball tables and drawer slides are commonly used, bearings, rollers, valves, and electronics, marine instruments, and the like. |
