Preparation, Characterization And Properties Of Degradable Linear Low Density Polyethylene soya Powder Blends

The linear low density polyethylene (LLDPE) was blended with soya powder by using Haake internal mixer at a temperature of 150°C and rotor speed of 50 rpm. The tensile properties were tested using an Instron tensometer. The thermal behaviors of the blends were analyzed using differential scanning...
