Effect of Natural Weathering on Tensile Properties of Low Density Polyethylene/Thermoplastic Soya Spent Powder Blends

Abstract:

The effect of natural weathering on tensile properties of low density polyethylene/ thermoplastic soya spent powder (TSSP) was studied. TSSP was produced by mixing the soya spent powder (SSP) with glycerol. Both blends were prepared by using internal mixer (brabender) at 150 °C with the SSP/TSSP content ranged from 0 to 25 wt%. Then, all the dumb-bell samples were exposed to Perlis environment located at Kubang Gajah, Perlis for 6 months period. The tensile properties were tested by using a universal testing machine (UTM) according to ASTM D638. LDPE/SSP blends presented lower strength and elongation at break (E_b) than LDPE/ TSSP blends meanwhile there were no Young’s Modulus values for 20 wt% onwards of both blends due to the brittle samples after 6 months of weathering.
