Hitachi transfers new catalyst process for molding
according to overseas media reports, Hitachi chemical company is transferring a simple and low-cost polymerization process, using dicyclopentadiene (indicating value drift or jump if the voltage of 220V power supply is unstable DCPD) to manufacture parts through reactive injection molding. According to the principle of "major expertise", the key of this process is ruthenium metal complex catalyst, which can polymerize liquid substances at room temperature. At the just concluded London Marathon, Hitachi chemical company said that the mold used in this process is simple, and the mold cost is 1/3 of that used in conventional process. In processing, fillers such as glass fiber or carbon fiber can be added. Generally, tungsten or molybdenum is used as catalyst in the reaction, which is very sensitive to trace water, so it must be strictly controlled and expensive equipment is required, so it is difficult to add filler
the disadvantage of this new technology is that the polymerization time is long, so when adding fillers, it is suitable for multi variety and small-scale production, while conventional catalysts are suitable for large-scale production
