  • Blends of recycled resins with metallocene-catalyzed polyolefins
    Patent number: 11746219
    Abstract: A recycled resin composition with significantly improved stress crack resistance and impact properties with minimal loss of stiffness. The recycled resin composition is a blend of at least one recycled resin (PCR and/or PIR), at least one virgin high density polyethylene and at least one virgin metallocene catalyzed linear low density polyethylene. The recycled resin composition can have a flex modulus @0.05 in/min of 110,000 psi to 180,000 psi, as measured by ASTM D790, Proc. A 1% Secant Modulus; and/or an ESCR, as measured by 100% Igepal Cond B, ASTM D1693, of about 10 hr to about 75 hr.
    Type: Grant
