Characterization and biodegradability of foam based on coconut flesh waste-filled high density polyethylene

Polymer foam biocomposites based on HDPE/coconut flesh waste were successfully produced by an extrusion foaming process. The compounding of the HDPE with coconut flesh waste was performed via a twin screw extruder which blends the materials with dicumyl peroxide (DCP) and chemical blowing agent (ADC...
