Abstract. The effect of filler addition and coupling agent content on the mechanical properties and morphology of wood plastic composites was examined. Using wood flour as the rein- forcement filler and recycled expanded polystyrene as the thermoplastic matrix polymer, a particle-reinforced composite was prepared using a co-rotating twin-screw extruder. In the sample preparation, four levels of filler loading (10, 20, 30, and 40 wt%) and three levels of coupling agent content (1, 2,& ...

This study examines the effect of particle size and wood flour content on the properties of polystyrene filled with white oak flour. wood-plastic ratios 10:90, 30:70 and 50:50% (wt/wt) and particle size 40, 50, 65 and 100 mesh were used. Tensile, bending and impact bending strength as well as the melt flow index were evaluated. Additionally, composite density and water absorption capacity were also tested. Scanning electronic microscopy revealed good adhesion& ...

The effects of size and concentration of wood particles on the properties of composites, obtained by extrusion, were evaluated based on polystyrene and wood particles from Eucalyptus globulus Labill. wood-plastic ratios were 10:90, 30:70, and 50:50 (weight / weight), and wood particles were retained in 40, 50, 65, and 100-mesh sieves. The density, flow index, water absorption, and the mechanical properties were evaluated. Scanning electron microscopy revealed poor adhesion& ...

Applied coatings and coupling agents, polystyrene-block- poly(styrene-co-methacrylic acid) (or PS-P(MAA-S and polystyrene-block- poly(styrene-co-acrylic acid) (or PS-. P(AA-S , were produced using the FRRPP process. (Caneba 1992). Base polystyrene material used to generate the composites was obtained from Dow Chem- ical (Styron 685D, with number average molecular weight of 270,000 Da). The PS-P(AA-S) copolymer& ...

In this work, the potential for usage recycled polystyrene and wood flour wastes as materials for development wood plastic composites was evaluated. The effects of wood flour loading and coupling agent addition on the mechanical, dynamic mechanical and morphological properties of polystyrene wood flour composites were examined. The results showed that the mechanical properties decreased with the wood flour loading. However, an improvement in composite compatibility was.

wood-plastic composites are probably one of the most dynamic sectors of today's plastic industry. Although the technology is not new, there is growing interest in the new design possibilities offered by this marriage of materials. In the world, polystyrene (PS) is the third most utilized thermoplastic after polyethylene (PE) and polypropylene (PP). The uses of PS are different from those of PE and PP because PS's glass transition temperature (Tg) is approximately 90ºC, and PS is rigid and& ...

Abstract. polystyrene (PS) from packing materials and plastic cups was reinforced with 30 and 50% wood flour through a blending process with and without a commercial compatibilizing agent. The processability of the pure recycled polystyrene (rPS) and wood rPS composites was studied in terms of the torque of the mixing process; this was then compared with that of a commercial virgin multipurpose PS. The physical and mechanical properties were compared with& ...
