The Use of Wood Plastic Composite Material in Various Countries

As currently envisaged, the Chinese wood plastic composite material according to the basic raw materials can be divided into two main types: One kind is polyolefin-based WPC decking composite materials, which are mainly based on polyethylene (PE) and polypropylene (PP). HDPE is more widely used in China. Wood deck and rice husk powder are mainly used as a modified reinforcing agent for wood fiber, and powder materials made from bamboo, wheat straw, cotton stalk, bagasse and coconut shell are also developed according to local conditions. Recently, it was reported that the waste reed was successfully used to make powder, giving full play to the characteristics of comprehensive utilization of resources. Another kind is polyvinyl chloride (PVC) composite deck materials, which PVC plastic generally use new materials, also mixed with a small amount of recycled materials. Less wood fiber is added. Because the proportion of PVC deck plastic is large, it is generally micro – foam treatment.

The Usage of Wood Plastic Composite Decking Basic Materials

The use of basic materials of WPC in China is similar to that in North America. Japan, which used to use mostly new plastics material, is increasingly using recycled materials and has strict requirements on the composition and purity of recycled materials.

The Use of Wood Plastic Composite Material Products in Europe

The use of plastic base materials in Europe is quite different from that in China. Since WPC was widely used in automobile interior decoration at the beginning, most plastics in Europe were polypropylene (PP). In 2005, PP accounted for 82%, polyethylene (PE) accounted for 10%, and PVC only accounted for 8%. By 2010, the share of PVC has increased to 20%, while PP has shrunk to about 70%. By 2012, after several years of market development, WPC decking in Europe was widely used in paving boards and fences. Because PE was cheaper and it was easier to get recycled PE than recycled PP, the share of PE increased to 32%, PVC to 28%, and PP to 40%. But in the injection molding of PP – based products still accounted for 93%.

Sources and Processing Methods of Wood Plastic Composite Decking Products in Various Countries

China’s wood fiber industry is quite different from its foreign counterparts, mainly due to its sources and treatment methods. China is an industrial manufacturing country with a large number of grain, bamboo and timber processing enterprises. The raw materials used in China’s wood and plastics industry basically come from the by-products and scraps of these processing enterprises. The raw materials of wood fiber are basically powders, fragments or shavings after certain drying and processing procedures before processing, with simple processing procedures and low cost. However, there are few foreign agricultural and forestry processing enterprises. The raw materials used in the wood and plastic industry are basically waste wood from buildings and some wood secondary branches. The production process includes crushing, grinding, drying and modification stages, and the processing cost is relatively high. In Europe, wood fiber, the modified reinforcing agent of wood plastic composite material products, accounts for 82% for extrusion molding, other is pulp, rice husk, etc., and 80% for injection molding. For wood and plastic interior decoration of automobile, natural fiber is mainly flax, others are jute and hemp, etc. Generally speaking, compared with its counterparts in other countries, China has its own unique advantages, which requires each user to carefully consult the product information purchased, and only by knowing clearly can the most suitable product be purchased. If you are still worried about decoration products, you can first come to Seven Trust to see some wood plastic composite decking products, if you consult us, you can get a sample and quotation, which can help you more easily understand the product, and decide which kind of product to choose.
