Ethylene polymerization catalyst
      Our polyethylene catalyst products include Ziegler Natta (titanium magnesium) catalysts, chromium based catalysts,metallocene catalysts, with over 20 brands.The product is suitable for various polyethylene production processes, such as Univation, Innocene, Borstar, CX, Hostalen, Spherilene, etc.

      Efficienteconomical removal of impurities from olefins is a serious problem for ethylenepropylene producers.The new generation of highly active polymerization catalysts have increasingly high requirements for impurities in feeds, such as COS, H2S, H2O, CO, O2, HCl, organochlorides, arsenic,phosphines, which can lead to the loss of catalyst activity. The list of our main adsorbent products is as follows:
