  • Polypropylene blend
    Patent number: 12729296
    Abstract: A composition is disclosed comprising a blend of 90-99 wt %, based on the blend, of a random propylene copolymer having an melt flow rate (MFR 230° C./2.16 kg) of 15-40 g/10 min and containing 1.5-2.5 wt % ethylene, and 1-10 wt %, based on the blend, of an ethylene based plastomer having a density of 860-915 kg/m3 and an MI2 (190° C./2.16 kg) of 0.5 to 25 g/10 min. The blend preferably has an MFR of 15-35 g/10 min and a flexural modulus of 700-1300 MPa.
