Evaluation and testing of mechanical properties of wood plastic ...Abstract. The wood plastic composites (WPCs) are made using matrices of recycled polypropyl- ene with sawdust (pine wood flour) as filler. Corresponding WPCs are also made using virgin plastics (vPP, virgin polypropylene) for comparison with the recycled plastic-based composites. All varieties of these WPCs are made through melt compounding and injection molding with varying formulations based on the plastic type (PP, polypropyl- ene), plastic form (recycled and virgin), wood ...【Get Price】
