What is wpc

Wood plastic composite materials (WPCs) are composite materials composed of wood elements combined with plastic fibers. WPC can be made entirely from recycled materials and plastic powder obtained from wood product manufacturing facilities. WPC, also known as composite wood, is widely used in the construction of outdoor deck flooring, prefabricated houses, park benches, door frames, and indoor and outdoor furniture. This article explains the manufacturing, characteristics, and advantages of WPC in architecture.



Manufacturing of Wood Plastic Composite Materials (WPC)

Wood plastic composite materials are made by fully mixing ground wood particles with heated thermoplastic resin. Finally, the entire mixture is squeezed into the desired shape. Commonly used thermoplastic resins include polystyrene (PS), polylactic acid (PLA), and polypropylene (PP).



The mixing and extrusion processes vary depending on the manufacturing facility. WPC contains organic raw materials that need to be processed at lower temperatures than traditional plastic composites to facilitate extrusion and injection molding. The ratio of wood to plastic in composite materials determines the melt flow index (MFI) of WPC. A large amount of wood leads to lower MFI.



Characteristics of Wood Plastic Composite Materials (WPC)

WPC is a combination of various substances prepared with a paste like texture. Therefore, they are molded into any desired shape and size.



WPC can dye or color to match the required design specifications.



Compared to ordinary wood, WPC is aesthetically and overall durable, as this composite material has moisture-proof and anti-corrosion properties.



WPC is more heat-resistant than typical wood.



The drilling, planning, and polishing work on WPC is similar to normal woodworking work.



Adding additives during the WPC manufacturing process results in better dimensional stability of the product compared to regular wood.



Advantages of Wood Plastic Composite Materials (WPC)

WPC materials are termite resistant and waterproof.



WPC boards provide good surface finish without the need for painting, dyeing, and oiling.



WPC materials require less maintenance and can withstand extreme weather conditions.



Compared to ordinary wood, WPC materials are more durable and have a longer service life.



The WPC floor is anti slip.



WPC materials come in different colors and are coated with different textures.



WPC can be hot formed into any curved or curved shape.



This material is UV resistant, so it will not fade when used outdoors.



WPC is made of recycled wood and plastic materials. Therefore, it is a sustainable and environmentally friendly material.
