What is POLAR PVC Foam Board?
POLAR is a premium lightweight expanded PVC foam board engineered for high‑quality visual communications where surface smoothness and printability are crucial. With a finely cellular core and bright white, low‑gloss satin surfaces, it offers an exceptional foundation for digital printing, screen printing, vinyl application, and more.
Part of 3A Composites’ graphic display range, POLAR balances weight, rigidity, and surface quality. Its uniform density and fine-cell structure ensure precise machining and fabrication, ideal for both flat panels and complex three-dimensional displays.
Why Choose POLAR Over Standard PVC Foam Boards?
- Superior Surface Quality: Ultra‑smooth, uniform face optimized for vibrant digital prints.
- High Stiffness‑to‑Weight: Rigid yet lightweight for easier handling and installation.
- Consistent Structure: Uniform density and fine cells for predictable fabrication and clean edges.
- Dimensional Stability: Resists warping across temperature and humidity variations.
- UV & Weather Resistant: Formulated for temporary outdoor use with minimal degradation.

Fabrication & Installation Recommendations
Printing & Finishing
- Cleaning: Wipe with isopropyl alcohol before printing.
- Edge Finishing: Sand or route edges; apply paint if desired.
- Vinyl Application: Use PVC‑rated pressure‑sensitive films.
- Painting: Prime and use acrylic paints for best adhesion.
- Laminating: Compatible with PS‑rated overlay films.
Fabrication
- Cutting: Table saws, panel saws, CNC with carbide‑tipped blades.
- Drilling: Twist drills, moderate speed, clear flutes often.
- Routing: Carbide bits, controlled feed to avoid melting.
- Thermoforming: 250–300°F (120–150°C), pre‑dry material.
- Fastening: PVC screws or adhesives; allow for expansion.
Installation
- Thermal Expansion: ~1/8″ gap per 4′ length in varying temps.
- Adhesives: Use solvent‑based or two‑part epoxies rated for PVC.
- Hardware: Corrosion‑resistant fasteners for outdoor use.
- Edge Support: Brackets or frames for large vertical panels.
Frequently Asked Questions About POLAR PVC Foam Board
How does POLAR compare to other PVC foam boards?
POLAR’s fine cell structure and smooth surface deliver superior edge finish and print quality. It outperforms economy boards in stability, durability, and visual appeal for premium signage.
Can POLAR be used permanently outdoors?
Designed for 6–12 months of outdoor use. For permanent exposure, use under cover or choose ACM or HDO plywood for longevity.
What’s the best way to join panels?
For invisible joints, use PVC solvent cements or two‑part acrylic adhesives. Plastic screws with oversized holes work for mechanical fastening without splitting.
Is POLAR recyclable?
Yes—recyclable through PVC programs where available. Fabricators can return scrap for reuse; recycled-content variants are also offered.
