The main materials of WPC boards (wood-plastic composite boards) include thermoplastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and plant fibers such as wood powder, rice husks, and straw. These materials are processed by extrusion, molding or injection molding, and are environmentally friendly, durable, and easy to process.
Specific ingredients and proportions
The ingredients of WPC boards mainly include the following:
Wood powder: Usually more than 50% of wood powder is used, which can be waste wood, rice husks, straw, etc.
Plastics: Commonly used plastics include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc.
Additives: Including coupling agents, UV stabilizers, foaming agents, etc., used to improve the performance and processability of materials.
