1. Product Description
POM: namely, polyformaldehyde, polyformaldehyde scientific name polyoxyformaldehyde (referred to as POM) also known as Sai Steel, special steel. It is obtained by polymerization of formaldehyde and other raw materials.
Pom-h (polyformaldehyde homopolymer) and POM-K (polyformaldehyde copolymer) are thermoplastic engineering plastics with high density and high crystallinity. It has good physical, mechanical and chemical properties, especially excellent friction resistance.

Application
At a lower cost than many other engineering plastics, POM is replacing some of the markets traditionally occupied by metals, such as zinc, brass, aluminum and steel for many parts. Since its inception, POM has been widely used in electronic, electrical, mechanical, instrument, daily use, light industry, automobile, building materials, agriculture and other fields in many new fields, such as medical technology Sports equipment and other aspects, POM also showed a good growth trend.
