Description
KAPA graph is the premier presentation-grade foam board in the high-performance KAPA range, specifically engineered for graphic arts, architectural modelling, and museum-quality displays. Featuring a solvent-resistant polyurethane (PUR) rigid foam core wrapped in deep black, acid-free cellulose liners, it delivers an unvarnished, velvety matt finish that absorbs light and ensures non-reflective, professional results.
Why Professionals Choose KAPA Graph
- Solvent Resistance: Unlike standard polystyrene alternatives, the high-spec PUR core is completely resistant to solvent-based adhesives, cyanoacrylate (superglue), and spray paints, allowing for rapid assembly and custom finishing without risking structural melting.
- Precision Crumble-Free Edges: The high-density polyurethane core cuts with extreme accuracy without fraying or shedding loose beads, yielding pristine, burr-free edges on intricate scale models and topographical layouts.
- Velvety Archival Surface: The premium black cellulose liners are pH-neutral and completely acid-free. This guarantees long-term stability, preventing mounted photographs, drawings, or artwork from degrading over time.
- Superior Adhesive Bonding: The unvarnished paper surface provides exceptional grip for fast-setting PVA, universal glues, and mounting tapes.
Essential Tools & Workability Tips
- Cutting Precision: Always use an exceptionally sharp scalpel or craft blade paired with a heavy-duty metal ruler. Make several light, successive passes rather than forcing a single deep cut to guarantee perfectly vertical, clean edges.
- Forming Curved Elements: Gently score through just the outer paper liner on one side to flex the inner foam core into smooth, controlled architectural bends and 3D shapes.
- Core Colour Note: Due to specialized manufacturing processes, the inner PUR foam core is a deep, uniform dark grey rather than pitch black, providing a stylish visual boundary for structural layouts.
Choosing Between KAPA Graph and KAPA Line
Both boards share the same solvent-resistant, crumble-free PUR core. Your choice depends on whether your project requires an unvarnished presentation finish or a versatile structural workhorse:
| Feature | KAPA Graph | KAPA Line |
|---|---|---|
| Description | Premium exhibition board featuring acid-free, pH-neutral paperboard with a deep matt, velvety finish. | Highly versatile all-rounder featuring coated, bright white chromo-substitute cardboard layers. |
| Key Advantages | Completely non-reflective surface, ideal for photography. Acid-free construction prevents yellowing over time. | Economical and superb for direct digital printing. Paper layers peel away easily for texture carving. |
| Considerations | Positioned at a higher investment level. Inner foam core is a dark grey rather than pure black. | Slight surface sheen, making it less suited for zero-glare final exhibition displays. |
| Best For | High-end client presentations, portfolio mounting, pristine museum models, and photographic backdrops. | Architectural models, structural frameworks, rapid prototyping, and detailed texture engraving. |
