Application Progress of Wood Plastic Composite Product
In recent years, the wood plastic composite material industry has developed well both in technology and in application fields. From the perspective of performance optimization, cost control and other research aspects, the wood plastic composite material has evolved from the initial generation of products to the current second generation and third generation of products. At present, the latest research results of wood-plastic composite materials mainly include second-generation wood-plastic products, pressed flower wood-plastic products and PVC deck products.

Second generation wood plastic products
The co-extrusion technology reduces the cost of wood-plastic composite products with the same performance and opens up a new way to save the cost of second-generation wood-plastic products. In recent years, Europe and the United States co-extrusion wood plastic products on the market more and more, is not only the traditional high-end wood plastic wall panel, fence use wood plastic co-extrusion decking, even the common floor, fence, cladding, template also more and more use wood plastic co-extrusion, the current wood plastic co-extrusion products account for the amount of wood plastic products has more than 50 ~ 60%, wood plastic co-extrusion has become a mainstream wood plastic products trend. At present, wood-plastic co-extrusion materials mainly include PVC, PE and acrylonitrile – styrene-acrylonitrile plastics (ASA). At present, the domestic production of wood-plastic products is mainly with recycled materials, so the application of wood-plastic co-extrusion technology is more necessary and urgent, otherwise it will soon be eliminated by the market. There is no need to add anti-aging agent, pigment and other materials in the base of co-extrusion wood-plastic products, and the thickness of the co-extrusion surface layer is about 0.5mm, which reduces the cost by more than 65%.
Press flower wood plastic products
With the improvement of people’s living quality, wood and plastic of single design and color cannot meet customers’ aesthetic needs. People have higher and higher spiritual requirements and are more inclined to get close to nature. In order to achieve the wood plastic beautiful, practical, simulation, plasticizing and other requirements, press flower wood plastic products came into being. Pressing flower wood plastic products more and more tend to complex texture, retro. At present, the most widely used technology is archaized deep embossing technology and online embossing technology. Online embossing commonly known as hot embossing, that is, before the temperature of the wood plastic profile at the die mouth is lowered, the original pattern is largely retained, increased the visual sense and three-dimensional sense of pressed flower, wood and plastic products, the wood plastic industry in the field of decoration has been developed and developed.
