PVC WPC Foam Board Machine: Technical Guide & Factory Selection Tips
PVC WPC foam board machines produce one of the most versatile and commercially successful building and furniture materials in the world. This guide explains the technology, formulation science, machine types, and selection criteria you need to make the right investment.
What Is PVC WPC Foam Board?
PVC WPC (Wood-Plastic Composite) foam board is a rigid, lightweight, closed-cell foam sheet produced by extruding a specialised compound of PVC resin, calcium carbonate filler, wood flour, chemical foaming agent, stabiliser, and lubricant system.
Core advantages over solid wood, MDF, and plywood include complete waterproofing, termite resistance, zero formaldehyde emissions, easy machining, and excellent paintability — making it a preferred substrate in furniture, interior fit-out, and signage.
