SLH-211-A

features and uses

SLH-211-A catalyst is a new type of chromium polyethylene catalyst with special SiO2 carrier, which is an inorganic chromium catalyst, suitable for Univation, Innovene, GPE, Spherilene C, Spherilene G, etc. Vapour phase polyethylene process in dry and condensation mode, with a catalyst activity of 6000~12000 KgPE/Kgcat, which has been reactivated. 12000 KgPE/Kgcat, reactivation has been completed, users can be directly used in the plant for the production of medium molecular weight distribution of polyethylene resins, mainly for the production of high-density film, PE80 pipe, medium and hollow products.
