POM GC-25日本宝理--POM was developed by DuPont company in the late 1950s. It is one of the three major general engineering plastics in the world. POM has the hardness, strength and steel properties of metals, excellent fatigue resistance and elasticity. POM also has good chemical resistance. POM has been widely used in electronic and electrical, machinery, instrumentation, daily light industry, automobile, building materials, agriculture and other fields since its production. Because the cost of POM is lower than other engineering plastics, POM has replaced the market occupied by metal, and it also shows a good growth trend in new application fields, such as medical technology, sports equipment and so on.
