Summary: To evaluate the performance of recycled high density polyethylene for pipe applications, blends containing 10, 30 and 50% of recycled in a PE T100N matrix were prepared and characterized using several instrumental analysis methods. The thermal analysis was performed by differential scanning calorimetry and thermogravimetry in the temperature ranges [23 °C, 300 °C] and [25 °C, 550 °C], respectively. Other technics as DMA, FTIR, XRD and MFR were used. The experimental results have showed that incorporation of recycled PE in PE T100N leads to poorer properties and it requires an upgrading with suitable additives.
