Wood–Plastic Composite Technology SpringerLink

Jun 4, 2015 An important constraint for polymers used in WPCs is requiring process conditions (melt temperature, pressure) that will not thermally degrade the wood filler. Wood degrades around 220 °C; thus, general-purpose polymers like polyethylene and poly vinyl chloride are typically used for manufacturing WPCs 【Get Price】

Wood-Plastics Composites Done Right : Plastics Technology

Apr 26, 2012 Counter- and co-rotating extruders can process wood fiber at moisture levels higher than 1% and 4% respectively, but at the expense of throughput. Reducing the This is important in WPC production because celluloses and lignin thermally degrade at temperatures above 190 C (374 F). Figure 1 shows 【Get Price】

potential uses. The markets for WPC decking lumber have been expanding recently and new applications are being pursued. Door and window components, deck handrails and fencing are other mar- kets for the WPC industry. The flexibility of manufacturing methods and product performance attributes provide the potential 【Get Price】

Development of a Wood Plastic Composite Extruder - OMICS

Sep 4, 2017 [11] divided the WPC manufacturing process into two main parts. The first part consisted of compounding the material; using a twin- screw extruder. The second part was to obtain profiles via single-screw extruder or use injection moulding to obtain a product resembling the wood in look and properties. 【Get Price】

Processing considerations for wood-plastic composites - Green Dot

A properly designed manufacturing process can bear most of the burden of reducing the presence of moisture. In an operation designed to first-and-foremost produce wood-plastic composite materials, much of the machinery in the facility should be dedicated to drying. Organic fillers need to be dried properly before being 【Get Price】
