1.1. Short description of WPC The classic composition of WPC is represented as a polymer (polyethylene, polypropylene or polyvinyl chloride), a filler, binder additives and dyes. First, all of these components are mixed in a mixer and then the granules are produced from this mixture. Some manufacturers pass the granulation stage.

Wood–plastic composites (WPCs) are composite materials made of wood fiber / wood flour and thermoplastic (s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA). In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.

2021年2月1日 · Wood-plastic composite (WPC) material is a thermoplastic engineering wood product, made of wood fibers (or plant fibers) and polymer plastic through a specific process, with excellent anti-corrosion properties, waterproof properties, thermal insulation properties and easy processing properties, etc. (Ashori, 2008), and is widely used in building...

Wood plastic composites (WPCs) is one of crucial and potential engineering wood products that has been extensively employed in the fields of landscape, transportation, municipal engineering and building construction. It has gradually been used to …

This fact sheet summarizes some of the basic manufacturing steps, physical and mechanical properties, as well as major uses of WPC. Wood plastic composites are widely used in the U.S. They are manufactured by mixing wood particles as fine as flour and recycled plastics.

2024年7月1日 · Wood polymer composites (WPCs) combine thermoplastic polymers as a matrix and lignocellulosic fibers as a dispersed phase. Comprehensive WPCs formulations, critical interphase modifications and characterization were discussed.

2021年8月24日 · Wood-plastic composites (WPCs) entered the market in the 1990s; they are usually composed of up to 50% w/w of wood flour, thermoplastic polymers (polypropylene, polyethylene, polyvinyl...

This book describes the basic physical and mechanical properties of modern WPC, such as tensile and compression strength, and hardness. Also, the influence of climatic factors on the performance properties of products from WPC is described, while the thermal and rheological properties of WPC materials are considered, which directly affect the ...

2024年6月21日 · Co-extruded WPCs (Co-WPCs) are multilayer composites, in which regular WPCs are coated with a protective shell layer through coextrusion. The core-shell structure of Co-WPCws provides a way to overcome the shortcomings of WPCs by modifications specific to the composite surfaces.

WPCs are composite materials made primarily from a blend of wood (or wood-based materials like wood flour) and thermoplastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA).
