PVC Foam Board (also known as Expanded PVC or Sintra Board) is a lightweight, rigid plastic sheet made primarily from PVC resin, together with calcium carbonate, foaming agents, stabilizers, and other additives. It is manufactured through an extrusion foaming process, creating a lightweight board with a smooth surface, a uniform closed-cell structure, and reliable performance.

Thanks to its lightweight design, durability, and excellent workability, PVC Foam Board is a popular choice for advertising signs, display boards, exhibition stands, cabinets, furniture, wall panels, interior decoration, construction, and many other industrial applications.
