Physical and thermal properties of polypropylene/rice straw biocomposite foam

Polymer foam biocomposites based on polypropylene/rice straw (PP/RS) were successfully prepared by using an extrusion foaming process. The compounding of PP and RS was performed in a twin-screw extruder which was blended with crosslinker; dicumyl peroxide (DCP), blowing agent; azodicarbonamide (AZ)...
