PVC foam board is a popular plastic material used across advertising, construction, and furniture industries. However, not all PVC foam boards are the same. The two most common types—Free Foam PVC and Celuka Foam PVC (also called Skin Foam PVC)—have distinct characteristics, manufacturing processes, and applications.

This article explains the key differences and similarities between these two types of boards to help you choose the right one for your project.

What is Free Foam PVC Board?

Free foam PVC board is made through an extrusion process that allows the material to expand freely, resulting in a lightweight, low-density sheet with a fine closed-cell structure. The surface is generally matte and slightly rough, which makes it ideal for printing, painting, and lightweight displays.

Key Features:

• Low density, very lightweight

• Matte surface texture

• Excellent workability for cutting, engraving, and gluing

• Cost-effective for large-format or disposable applications

Common Applications:

• Advertising boards and signs

• Indoor display panels

• Promotional stands and exhibition props

• School project boards or model-making

What is Celuka Foam PVC Board?

Celuka foam PVC board is also extruded, but it passes through a cooling mold that forms a hard outer skin during production. This process results in a denser board with a smoother, glossier surface and significantly higher surface hardness. The inner core remains foamed, but the overall rigidity and surface finish are much better than free foam.

Key Features:

• Smooth and glossy outer skin

• Higher density and hardness

• Stronger impact resistance and durability

• Better dimensional stability and heat resistance

Common Applications:

• High-end signage and printed display panels

• Bathroom cabinets and kitchen boards

• Decorative wall cladding or partitions

• Door panels and waterproof furniture components

Which One Should You Choose?

If your project prioritizes light weight, easy fabrication, and lower cost, such as promotional displays or indoor signs, free foam PVC is likely the better option.

If you need a board with a smoother finish, stronger durability, or a structural role—like in cabinet making or wall cladding—Celuka foam PVC is more suitable.

Final Thoughts

Both free foam and Celuka foam PVC boards are versatile, water-resistant, and easy to work with. Choosing the right type depends on your project’s technical and visual requirements. Understanding the structural and performance differences ensures better material selection and cost control.
