Polyethylene Composition with Improved Stress Crack Resistance/Stiffness Relation for Blow Moulding
摘要:
The present invention relates to a polyethylene composition wherein (i) the composition has an MFR2 of 0.05 to 100 g/10 min, (ii) the environmental stress crack resistance ESCR measured according to the FNCT at 12 MPa and 23° C. in hours and the E-modulus EM measured according to ISO 527-2: 1993 satisfy the following relation: ESCR>−0.244 EM h/MPa+416 h (I).
