Comparative Investigation on the Properties Polypropylene- Sanding Fines and Dust Composites

Document Type : Complete scientific research article

Abstract

In this research, the sanding dust was used to manufacture wood –plastic composite its their properties were compared with wood flour–Polypropylene composite. Sanding dust and wood flour were separately mixed with of Polypropylene at three levels of 50%, 60% and 70%. Coupling agent (MAPP) was used at two levels (4% and 6%). Totally twelve composites were produced. The composites were manufactured using hot press. After preparation of test samples, mechanical properties (bending and hardness) and physical properties (water absorption and thickness swelling) were measured. Results showed that addition of both fillers reduced modulus of rupture and increased modulus of elasticity, water absorption and thickness swelling. The urea – formaldehyde resin present in sanding dust caused a reduction in mechanical and physical properties of polypropylene-sanding dust composite compared with polypropylene -wood flour composite at the same levels of fillers.
