Siv cov chromium catalyst txhawb rau ntawm silica gel, ethylene yog polymerized nyob rau hauv nruab nrab siab nyob rau hauv lub voj reactor los ua high-ntom polyethylene.
Kev ua thiab daim ntawv thov Nws tuaj yeem ua tiav los ntawm tshuab moulding, extrusion, txhaj tshuaj molding, thiab lwm yam. Nws yog dav siv hauv kev tsim cov yeeb yaj kiab, cov khoom siv hollow, cov fibers thiab txhua hnub sundries. Hauv kev tsim ntau lawm, txhawm rau txhim kho qhov ruaj khov ntawm polyethylene mus rau ultraviolet rays thiab oxidation, thiab txhim kho kev ua haujlwm thiab siv kev ua tau zoo, ib qho me me ntawm cov yas ntxiv yuav tsum tau ntxiv. Cov pa uas siv los tiv thaiv ultraviolet yog cov o-hydroxybenzophenone lossis nws cov alkoxy derivatives, thiab lwm yam. Tsis tas li ntawd, tshuaj tiv thaiv kab mob, tshuaj tiv thaiv kab mob, tshuaj pleev xim, thiab lwm yam kuj tau txuas ntxiv los nthuav cov ntawv thov ntau ntawm polyethylene.
