The usage of waste tire powder as dispersed phase in polypropylene matrix offers an interesting opportunity for recycling of the waste tire. In order to obtain ‘value added products’ from polypropylene (PP)/waste ground rubber tire powder (WGRT) composites, In this study, the foam processability of PP/WGRT composites is investigated using a single-screw foam extrusion setup and chemical blowing agent. The effects of formulations (i.e. WGRT content, blowing agent content, compatilizer), the processing parameters (i.e. Die temperature, screw speed), and the recycling times of PP on the cell size, cell density, cell morphology, and volume expansion ratios of PP/WGRT composites foams are investigated. |
