properties of wood-plastic composites are continuing to drive growth in wood replacement applications . north american wpc producers are seeking to translate wpc into other building product areas such as fencing trim board windows and wpc sheet for replacing plywood. wpc is .
wpc producers are seeking improved products with focus on physical property retention colour retention mould and mildew resistance. because the wpc industry is relatively young the long-term- 10-20 year durability of outdoor products like decking is still being proven in the field. to achieve good wpcs additives are .

material properties wood plastic composite (wpc) product lines are showing resilience in the face of the worst economic downturn in recent memory . as a result wpcs have grown into a billion-dollar-plus industry with more than 30 manufacturers competing in the north american market alone.
mechanical properties can be improved via applying longer fibers. three different lengths 5 15 and 25 mm of glass fibers were added to the wpc compounds to reinforce wpcs in an extrusion process. in addition continuous glass fibers were also embedded into the extruded wpc with 70 .

wpc in north america europe and now in asia is decking . tests conducted by wood k plus showed that ten regrinding and injection moulding cycles led to only small changes in mechanical properties and a colour change in lighter composites can be observed after several cycles.
north american wpc is recycled and 60-65 % is virgin plastic (klyosov 2007). below are brief descriptions of the most commonly used matrices. polyethylene pe. polyethylene is the most common plastic in consumer goods. there are various kinds of. pe and they are classified based on their density because of the ease .
