2. Usage .
POM has been widely used in electronic and electrical, mechanical , instruments, daily-use light industrial, automotive, building materials, agriculture and other fields. In many new fields of applications such as medical technology, sports equipment, etc., POM has a very low coefficient of friction and good geometric stability, particularly suited to the production of gears and bearings. It also has properties as a result of high temperature, it is also used pipe device (pipe valves, pump casing), lawn equipment, etc.
