What is the prospect of wood-plastic products?

When high-quality wood products are more and more favored by people, log products are more and more popular in cities, and the speed of forest disappearance is faster and faster, which sounds the alarm for the crisis that natural resources are about to run out. Fortunately, the development of plastic profile industry has largely replaced wooden doors and windows, which has alleviated the ecological crisis to a certain extent, but it still brings some inevitable shortcomings. For example, the texture and color of plastic profiles cannot surpass log products, so the cost performance is naturally greatly reduced. So can plastic and wood be combined to produce a high-quality product with high cost performance, environmental protection and practicality to replace plastic or wood products? Facts have proved that it is possible. A few years ago, some international experts thought about this problem and took practical actions, which achieved considerable results. For example, a few years ago, European countries that had participated in the research and application of plastic profiles earlier had taken the lead in introducing composite profiles made of wood fibers and plastics, which had been successfully applied in many aspects. It is said that in recent years, a company in Singapore has also successfully increased the filling amount of wood fiber by 50%, and the strength of doors and windows manufactured can also meet the requirements of relevant standards. The above shows that the research of wood-plastic composite profiles has achieved practical results, and its production and clinical application have taken a more important step. Although the production of wood-plastic composite profiles has become a reality, can it really realize the functions of wood and plastic and eventually replace them? This is probably a question of many people. Ok, now I will answer this question by comparing the functions of wood-plastic composite extrusion products with those of plastic products and wood products. After reading it, you may be able to solve some doubts.

Compared with wood, the appearance and texture of wood-plastic composite extrusion products are similar to wood, and they have the same processability and construction performance as wood. The density of the product is between 600~ 1000kg/m3, which varies according to the filling amount and foaming rate of wood fiber, and is generally around 600~800kg/m3, which is quite close to wood. The moisture content is about 2%, while the moisture content of wood is between 12%- 13%. Compared with logs, wood-plastic composite profiles have better water resistance and corrosion resistance, and have no natural defects of wood, such as cracking, warping, scarring and obvious color difference. We also know that in addition to mechanical and physical damage, wooden doors and windows have a combined weakness, that is, insects, such as termites and moths, and wood-plastic composite profiles can resist pests. In addition, the cross-section design of extruded products is flexible, and decorative structures and various functional structures can be designed. However, the functional structure and decorative structure of wood products are often limited by processing methods, and many decorative effects are difficult to achieve. Obviously, these are the advantages of wood-plastic composite extrusion products over wood products, and they are almost everywhere. Therefore, the future market of wood-plastic products is quite large.
