What is the development trend of plastic-wood composite products?

 

WPC Decking Board.jpgWith the industrialization of plastic-wood composite products, application researchers have discovered the defects of plastic-wood composite products, and the applicationrs have put forward higher requirements: to prevent aging and anti-decoloration of outdoor products for garden landscapes. Service life; good flame retardant performance for interior doors and windows and decorative parts materials; high mechanical properties for plastic-wood products supported by house base parts, which need to be enhanced and improved creep resistance. With the improvement of energy-saving voices, the construction industry has also put forward higher requirements for the energy-saving effect of plastic-wood composite products. Therefore, plastic-wood composite products are developing towards functionalization and high added value: flame-retardant, reinforced, anti-aging, creep-resistant, thermal insulation and so on. In addition, the selection of wood-based composite materials is also diversified and multi-variety, including raw wood powder and plastic.


In terms of molding process, the extrusion molding process is the mainstream method of molding and processing of plastic-wood composite products, and is mainly used for developing profiles, pipes and plates. With the diversification of plastic wood products, such as plastic-wood multi-layer composite pipe and plastic wood micro-foaming floor, higher requirements are put forward on the extrusion process, and its research and development direction is multi-layer plastic-wood composite co-extrusion and coating. Extrusion, coextrusion of steel/plastic wood, coextrusion of plastic/plastic wood, etc. Injection molding is mainly used for plastic wood parts and auto parts, etc. Its new development trend is large-scale product development and engineering plastics, such as ABS plastic wood products.

 

The molding method and process are the new trends in the development of plastic-wood composite products, such as multi-layer multi-station intermittent, hot extrusion cold pressing and continuous rolling, especially the development of large-scale plastic wood products such as wide-width thick-walled plates. The molding process can greatly improve work efficiency, reduce production costs, and produce products that are difficult to achieve by other methods.
