SCG-4

features and uses

SCG-4 catalyst is a chromium-based polyethylene dry powder catalyst suitable for Uivation process, catalyst activity 4000 ~ 6000 KgPE/Kgcat, mainly used for the production of medium molecular weight distribution of linear low-density polyethylene products in the actual production of the main production of wire and cable sheathing. The catalyst is intended to replace the imported UCAT-B400 (F-4) catalyst for the production of LLDPE with medium molecular weight distribution (MFR=50 ~ 90).
