The Ecoflex and polyurethane were used as biodegradable polymer and impact modified respectively. This research was ascertained tile way to reduce the processing cost of PMMA sheet and the industrial waste by recycled PMMA scrap into the production process. The r-PMMA/PMMA-blend-PU/Ecoflex sheet was studied potential degradation by landfills for six months. After degradation the percentage of weight loss of specimens was increasing depend on amount of Ecoflex content and degradation period. While, the surface morphology of r-PMMA/PMMA-blend-PU/Ecoflex sheet after six months was damaged and demonstrated that Ecoflex had an effect on PMMA-blend-PU sheet in potential biodegradation. The mechanical and physical properties of r-PMMA/PMMA-blend-PU/Ecoflex sheet were described. Finally, the impact strength of r-PMMA/PMMA-blend-PU/Ecoflex sheet from this research, it is possible to use r-PMMA and Ecoflex in the acrylic casting sheet product.展开更多
