Effect of Species and Particle Size on Properties of Wood-Flour In this case, the composite material was 40% by weight wood flour. Particle size did not affect specific gravity, but it did affect other properties. Melt flow index, heat deflection temperature, and The use of scrap-wood-derived fillers for thermoplastics has been accepted by the plastics industry in recent years. Wood-derived

Low bulk density of wood flour vis-a vis plastics. ( 0.5). Low specific gravity of wood; Low thermal stability of wood; Tendency to absorb moisture. The Turn Around
DENSITY RANGE OF COMPRESSION-MOLDED thermoplastic resins have been developed pri- marily by the plastic industry. The wood is usually finely ground and added as a filler. (Kokta et al. 1989) but may comprise as much as 50% by weight of the composite. The final. SG of an extruded component of this type, made with a 0.9 SG polypropylene thermo- plastic resin
WOOD POLYMER COMPOSITES Marc H. Schneider Solid wood. (lumber) or any wood composite (such as wa- ferboard and medium density fiberboard) can be used to make WPC, although solid wood is .. material is formed regardless of the original wood density. This can be valuable when dark, tropical woods are being simulated using light- er, temperate zone woods.
Physical and bending properties of injection moulded wood plastic wood plastic composite (WPC) require solving two major constraints; technique and formulation before their design value . The average specific gravity of all samples was about 1.15. Table-3 shows the moisture content and specific gravity for the WPC boards produced in first experiment, whereas, Table-4 shows the.
