WPC foam board (WPC board), maybe not many people know it. WPC foam board, also called wood plastic composite board, is a hard expanded plastic PVC board.
Its main components are polyvinyl chloride (PVC), additives, and a small amount of wood or bamboo powder. It is the wood powder that gives the WPC foam board a natural wood-colored appearance that looks like MDF.
Thanks to the foaming production process, the WPC foam board has a light weight, and a uniform and stable closed-cell structure. What is more valuable is that it is a waterproof, mildew-proof, termite-proof building board, suitable for use in humid environments and outdoors, such as cabinet boards, marine furniture boards. The WPC foam board is self-extinguishing from fire, and the flame-retardant enhanced version of the WPC foam board can reach the Class A of the ASTM E84 standard.
