THE POLYETHYLENE RESIN WITH EXCELLENT ESCR AND STIFFNESS FOR BLOW MOLDING

摘要

The present invention relates to a polyethylene resin for blow molding and, more specifically, to a polyethylene resin for blow molding with optimal physical properties to have excellent environmental stress cracking resistance (ESCR), moldability and hardness when being applied to a middle-sized container of 10-30 liters. The polyethylene resin for blow molding, manufactured by a multi-modal process with a ziegler-natta catalyst and two or more reactors, has the weight average molecular weight of 350,000-400,000 g/mol and the molecular weight distribution of 12-25.
