Posachedwapa, chothandizira cha polypropylene cha metallocene chomwe chinapangidwa payokha ndi Beijing Research Institute of Chemical Industry chinamaliza bwino mayeso oyamba a mafakitale mu gawo la ring pipe polypropylene process unit ya Zhongyuan Petrochemical, ndipo chinapanga homopolymerized ndi random copolymerized metallocene polypropylene resins yokhala ndi magwiridwe antchito abwino kwambiri. China Sinopec inakhala kampani yoyamba ku China kupanga bwino payokha ukadaulo wa polypropylene wa metallocene.
Polypropylene ya Metallocene ili ndi ubwino wokhala ndi zinthu zochepa zosungunuka, kuwonekera bwino komanso kuwala kwambiri, ndipo ndi njira yofunika kwambiri yosinthira ndi kukweza makampani a polypropylene ndi chitukuko chapamwamba. Beihua Institute inayamba kafukufuku ndi chitukuko cha metallocene polypropylene catalyst mu 2012. Pambuyo pa mayeso ang'onoang'ono, mayeso a chitsanzo ndi kukonzekera kuyesa koyesa, idathetsa mavuto aukadaulo monga kapangidwe ka kapangidwe ka catalyst, njira yokonzekera ndi kukonza bwino ntchito yothandiza, ndipo idapanga bwino metallocene polypropylene catalyst. Ukadaulo wa propylene catalyst ndi kupanga zinthu zothandizira. Poyerekeza poyerekeza pansi pa mikhalidwe yomweyi ya polymerization, catalyst imakhala ndi ntchito yayikulu kuposa catalyst yotumizidwa kunja, ndipo mankhwala a polypropylene okonzedwa ali ndi mawonekedwe abwino a tinthu tating'ono komanso opanda agglomeration.
Kuyambira Novembala chaka chino, catalyst yamaliza mayeso a mafakitale motsatizana mu fakitale ya Hypol process polypropylene ya Yangzi Petrochemical ndi fakitale ya ring pipe process polypropylene ya Zhongyuan Petrochemical, ndipo yapeza zotsatira zabwino zotsimikizira. Mayeso a mafakitale awa ku Zhongyuan Petrochemical ndi nthawi yoyamba ku China kupanga polypropylene yachitsulo chosasinthika pa chipangizo cha ring pipe polypropylene, chomwe chakhazikitsa maziko olimba a chitukuko chapamwamba cha makampani a polypropylene a Sinopec.
