In the United States and Europe, plastic-wood composites’ history goes as far back as 40 years ago, plastic-wood composites were used in auto accessories, trains, and shipping boards. Since the 1980s, the demand in Northern America has surged because the application range expanded as suppliers gained more production know-how.
In high humidity, tropical or coastal areas, plastic-wood composites are extremely advantageous, particularly providing the waterproofing, mold-resistant, termite-resistant, and corrosion-resistant characteristics needed to prevent rotting or erosion. In addition to these essential qualities, plastic-wood composites generally offer a great advantage (over any wood) against warping, deforming and cracking. Near ocean or lakes, erosion may be reduced or eliminated. In the U.S., fences, pallets and planks (near hot springs) are made with plastic-wood composites. In Vancouver, Canada, benches made of plastic-wood composites are used in parks and on sidewalks. In 2000, statistics revealed that the demand for plastic-wood composites had drastically increased from a hundred thousand to millions of tons, and the demand reflected the substitution of common timbers for plastic-wood composites.
However, plastic-wood composites have some disadvantages. Plastic-wood composites can weight twice as much as normal wood and its unit price cost is higher, because polyethylene derives from gasoline, and crude oil prices fluctuate drastically. As a result, plastic-wood composite prices remain relatively high, and only when technological hurdles are overcame will WPC price be more competitive. For this reason, Jing Shing Industrial Company (JSI) then applies its proprietary JPW into patented assembly home series.
