Abstract: The catalyst SLC-S supplied from Shanghai Leader Catalyst Company Limited was industrially tested at SINOPEC SABIC Tianjin Petrochemical Company Limited. The activity，hydrogen sensitivity，copolymerization performance of the catalysts and the influence of the reduction ratio over them was studied. The bulk density，average size，fluidization density of the polymers was tested. The items above were compared with homebred catalysts of the same kind. The result was that the performances of SLC-S were better than the homebred catalysts of the same kind and the responses of the reduction ratio were not sensitive. The properties of the products was also tested，and it indicated that the products are of high quality.

Key words: LLDPE, catalyst, industrial application
