Why is POM called Saigang
The main reason is that the hardness of POM is relatively high. The Rockwell hardness reaches D80-85Z, which is a high-hardness material in engineering plastics. In terms of hardness, it is comparable to steel, and in other processing properties. , POM is also good, making some spare parts, bearings, gears, etc., is also good. Nowadays, engineering plastics is an emerging industry, many of which can replace steel, and have properties that metal materials do not have, such as insulation, wear resistance, acid and alkali resistance, etc.
