Waste Polyurethane Reinforced Polyester Composite, Production, and Characterization

In this research, new composite materials were improved by reinforcing the environment-polluting waste polyurethane (WPU) to unsaturated polyester (UP). Polyester composites produced with WPU, UP, methyl ethyl ketone peroxide (MEKP), and cobalt octoate (Co. Oc.). The effect of WPU on changes in density, Shore D hardness, thermal conductivity coefficient, stability, porosity obtained investigated. According findings, as ratio increased composite, both coefficient density decreased. hardness was been found decrease rate raised. use optimum ratios (7 wt.%) production some thermo-physical properties composite. high negatively affected surface morphology stability addition, parameters affecting optimized according response methodology (RSM).
