composite of wood and polystyrene

polystyrene/wood composites and hydrophobic - semantic scholar

abstract the combination of synthetic thermoplastic polymers and wood is normally problematic because wood surfaces are hydrophilic while typical thermoplastic polymers are hydrophobic. a possible solution is to use block copolymer coupling agents. in this work we show the use of a potentially useful synthetic method of producing hydrophilic-hydrophobic block copolymers as hydrophobic coatings and coupling agents in polystyrene! wood flour composites. in particular wood 【Get Price】

improvement of the mechanical properties of sawdust wood fibre

the mechanical properties of compression-moulded polystyrenes filled with sawdust wood residue of softwood and species have been investigated. the tensile modulus at 0.1% strain and the tensile strength elongation and energy at the yield point are reported. the suitability of sawdust wood residue as a filler for thermoplastics has been tested using two different mesh sizes (20 and 60) as well as by varying the weight percentage of fibres from 10% to 40%. moreover to 【Get Price】

characterization of composites based on expanded polystyrene

this paper aims to evaluate the potential for the use of recycled expanded polystyrene and wood flour as materials for the development of wood plastic composites. the effects of wood flour loading and coupling agent addition on the mechanical properties and morphology of wood thermoplastic composites were examined. in addition a methodology for the thermo-mechanical recycling of expanded polystyrene waste was developed. the results show that the mechanical properties 【Get Price】

thermal conductivity of composites made of wastes of wood and

in the present work a possibility of recycling sediments of woods and polystyrene packing remove from service in view to produce composite materials of wood has been examined. the composite materials consist in that chips or sawdusts of wood sorted in particles of varied dimension and mixed according to a granular composition well defined. the different components are assembled with glue obtained from polystyrene of packing dissolves in a solvent. the thermal conductivity λ 【Get Price】

thermal and mechanical properties of wood flour–polystyrene

27 jul 2010 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 those of 【Get Price】
