Antioxidants for Recycled Polyolefins
Why Recycled Polypropylene and Polyethylene Need Fresh Antioxidants Recycled polypropylene (rPP) and recycled polyethylene (rPE) may require additional antioxidant stabilization because previous processing and service exposure can reduce their resistance to further oxidation. Extrusion, melting, heat, and shear can contribute to polymer degradation, particularly when the material has experienced several processing cycles. Re-stabilization helps compounders […]
