The copolymerized formaldehyde project adopts advanced and stable production technology, which is clean and economical. Several sets of key equipment in the device are advanced equipment introduced from abroad, with high technology, high safety performance, high stability, good comprehensive performance and coloring. The annual production capacity of the production plant is 80,000 tons. Copolymerized formaldehyde (POM) is a high melting point, high density, high crystalline thermoplastic engineering plastic without branched chain. It has excellent mechanical properties, outstanding self-lubricating property, wear resistance and chemical resistance, fatigue resistance, dimensional stability and good creep resistance. It is one of the varieties closest to metal in engineering plastics. Can be used to replace copper, aluminum, zinc and other non-ferrous metals and alloy products. Have "capture steel", "super steel" said.
