Foamed plastic wood composites shine in the application field

The foamed plastic wood composite material is made by mixing plastic masterbatch, wood powder, filler, foaming agent and various additives in a certain proportion, and then introducing cells into the composite material during the molding process. The gas phase formed in the wood blend system can be achieved through the separation of dissolved gases, the vaporization of volatile gases, or the release of gases produced by chemical reactions.

The good cell structure inside the foamed plastic wood composite material helps to passivate the crack tip in the ordinary WPC and prevent the crack from propagating, so it can overcome the brittleness of the ordinary plastic wood composite material, lower impact strength and material elongation lower disadvantage. In addition, because the foamed plastic wood composite material contains a large number of cells and the material has large internal voids, the amount of resin used during preparation is greatly reduced, which relatively saves material costs and effectively reduces the density of the material (about unfoamed plastic wood 50% of the composite material, up to 0.6-1.0g/cm3), the sound insulation, heat insulation and cushioning effects of the material are also improved.

In addition, because the foam material has a lighter weight and is easy to transport, construct and install, it is expected to become a substitute for wood and plastic used in logistics packaging and other industries. Foamed plastic wood composite material is also an environmentally friendly material, with a wide range of materials (both recycled secondary fibers and waste plastics), low manufacturing cost, and it can be recycled and reused many times, reducing the amount of plastic used and reducing In addition to environmental pollution, it is also beneficial to protect forest resources. Although some domestic packaging material manufacturers and research units are working hard to develop foamed pure plant fiber cushioning packaging materials, in comparison, foamed plastic wood composite materials are still in use because they combine the advantages of wood and plastic. It has more advantages in performance, such as higher strength, better water resistance, lower price, and wider application range. In recent years, plastic wood micro-foaming technology has also been greatly developed, especially for PVC-based manufacturers. In order to meet product performance requirements, develop new processing techniques, introduce foaming technology, reduce material costs, and expand the scope of use of WPC. Foamed plastic wood composite materials can be used as light and high-strength parts required by the automotive industry, sports equipment, packaging, and heat preservation and heat insulation materials in the construction industry, and they shine in the application field.
