    Improved flexible, controlled dielectric constant material from recycled LDPE polymer composites by Noorunnisa Khanam, P.

    Published 2016
    “…In this study, recycled low density polyethylene (RLDPE) is developed with the addition of aluminum oxide (Al2O3) to have new polymer composites. The following wt% were used of the filler (1, 4 and 6 wt%). Tensile properties, Hardness, scanning electron microscopy (SEM) thermo gravimetric analysis, differential scanning calorimetry and dielectric properties were studied for these composites. 4 wt% Al2O3/RLDPE composites showed the optimum values of 15.52, 180.8 and 59.72 MPa for the tensile strength, tensile modulus and hardness were reported. …”
