ETHYLENE RESIN AND BLOW-MOLDED ARTICLE COMPRISING THE SAME

摘要

Disclosed is an ethylene resin which satisfies all of the following requirements [a] to [c]: [a] the environmental stress cracking resistance (ESCR) T as measured at 50°C in accordance with ASTM-D-1693 is 500 hours or longer when the flexural modulus is 1000 to 1500 MPa and 100 hours or longer when the flexural modulus is 1500 to 2000 MPa; [b] the melt tension as measured at 190°C is 50 (mN) or greater; and [c] the crack speed under melt drawing is 90 (m/min) or less. The ethylene resin is excellent in strength and moldability and can be used suitably for a blow-molded article (a hollow molded article).
