novel process development in post-forming of an extruded wood ...control of the process and the adhesion properties of the composite material. The results show that the quality of extruded, press-formed thermoplastic wood plastic composite products can be satisfactory and suitable for mass production, if right parameters are selected for the machine construction, and the process temperature is monitored and controlled. It is also shown that the mechanical post-processing stage can decrease material variation and thus improve the quality of the ...【Get Price】

Study of Wood-Plastic Composites with Reused High Density ...The composite material that emerges is called a wood-plastic composite, or WPC. The base materials were chosen because they both are waste materials from local industries. This means that the re usage of these materials may have an impact on local economy [9][11]. The study focused on obtaining mixtures of high-density polyethylene (HDPE) and sawdust having different particle sizes and several mass percentages. These materials were then characterized mechanically, after&nbsp;...【Get Price】

Wood-Plastics Composites Done Right : Plastics Technology26 Apr 2012 ... wood-plastic composite (WPC) products were first widely marketed in the early 1990s as weather-resistant decking. ... There are two significant mass-loss events in the TGA analysis: loss of water at 25 C to 125 C, accounting for 6.02% of the initial sample weight; and the decomposition of celluloses and lignin between 190 C and 400 C, accounting for ... Much of the plastic used in WPCs is recycled, and another significant fraction is wide- or off-spec virgin material.【Get Price】

Field and Laboratory Decay Evaluations of wood-plastic CompositesThe shortest initiation time and the most aggressive environment for decay of WPC samples were found at the sunny site in Hilo. Laboratory soil block culture testing showed weight loss and density decrease of experimental WPCs to depend on conditioning. Correlations between laboratory test results and WPC performance in the field are described.
