SCG-3

features and uses

SCG-3 catalyst is a chromium-based polyethylene dry powder catalyst for the Uivation process with a catalyst activity of 4000~6000 KgPE/Kgcat, which is mainly used for the production of medium molecular weight distribution HDPE products, mainly for military bags and films. The catalyst is intended to replace the imported UCAT-B300(F-3) catalyst for the production of HDPE with medium molecular weight distribution (MFR=50~90).
