Description
18mm PVC foam sheet is specifically designed for display fabricators, printing companies, exhibition contractors, and branding solution providers that require stronger panel rigidity than standard advertising sheets.
Instead of thinner PVC display boards that may bend during transportation or installation, the 18mm structure offers enhanced stability for large-format signage, freestanding display systems, promotional stands, and exhibition booth construction. Its lightweight foamed core reduces overall project weight while maintaining sufficient strength for commercial applications.
The board features a smooth and uniform surface that supports UV printing, vinyl graphics, screen printing, laminating, and decorative film applications. Combined with excellent machining performance, it allows advertising manufacturers to create customized shapes, display structures, retail fixtures, and promotional installations efficiently.
As a professional PVC foam board manufacturer, Zibo Kaichuang Plastic Co., Ltd. supplies customized advertising-grade PVC foam sheets to distributors, sign makers, exhibition companies, and branding agencies across global markets. The product is available in multiple sizes, densities, and packaging solutions according to project requirements.
Why 18mm Thickness Works Better for Advertising Structures
Many advertising projects require materials that are strong enough to remain flat while still being lightweight for installation.
The 18mm structure provides:
Better rigidity for large panels
Reduced bending during transportation
Improved mounting stability
Longer service life for displays
Easier fabrication than wood panels
This makes it a popular choice for exhibition and retail display construction.
Features
1. Moisture-proof: The water absorption rate of this 18mm PVC Foam Sheet is ≤1.0%, it is moisture-proof for a long time and will not become moldy. It will be a very practical material choice for humid environments such as bathrooms and kitchens, and does not require frequent replacement or maintenance.
2. Good stability: The plate has a bending strength of ≥20 MPa, an impact strength of ≥12 kJ/m2, and the material is hard and durable. It is capable of carrying medium weight and remains stable for a long time, and will not break or deform easily even in the case of collisions and falls.
3. Flame retardant: It has good self-extinguishing properties, can effectively prevent fire, and can be used very safely for a long time. And it doesn't release any harmful gases, such as nitrous oxide, making it safe even in high-temperature environments.
