  • Polymer composition for injection moulding
    Patent number: 8722807
    Abstract: The application relates to a polyethylene composition having a base resin, the base resin comprising (A) a first polyethylene fraction, and (B) a second polyethylene fraction, wherein the melt flow rate MFR5/190° c. of the first fraction is higher than the melt flow rate MFR5/190° c. of the second fraction, the flow rate ratio FRR21/5 of the polyethylene composition, defined as the ratio of melt flow rate MFR21-6/190° c. to melt flow rate MFR5/190° c., is within the range of 15-28, and 10 the melt flow rate MFR5/190° c. of the polyethylene composition is within the range of 0.5-1.1 g/10 min.
