A2 Fireproof Marble ACP: Balancing Architectural Aesthetics with Non-Combustible Safety

In modern commercial facade design, marble-effect ACP is the preferred choice for its lightweight nature and visual authenticity. However, for high-rise buildings exceeding 24 meters, A2-grade fire performance (per EN 13501-1) is the physical baseline for safety. Our series integrates inorganic non-metallic cores with premium aluminum skins to unify stone aesthetics and fire resilience.

To achieve the A2 fire-rated standard, the formulation of the core material must undergo rigorous precision control:

• Inorganic Core Composition: The core contains $ge 90%$ inorganic mineral content. According to the ISO 1716 Gross Heat of Combustion test, the Calorific Value (PCS) is strictly maintained at $le 3.0 MJ/kg$.
• Peel Strength and Stability: Despite the inorganic nature of the core, our continuous high-polymer thermal composite process ensures a $180^{circ}$ peel strength of $ge 7.0 N/mm$.
• Operating Range: Engineering integrity is guaranteed under extreme thermal cycling from $-50^{circ}C$ to $+80^{circ}C$, ensuring zero risk of delamination between the aluminum skin and the core.

To withstand wind-blown sand erosion and surface mechanical friction common in exterior applications, we utilize an enhanced 3-coat PVDF system:

• Surface Hardness: The coating achieves a pencil hardness of $2H$ or higher, effectively resisting minor scratches during construction and long-term building operation.
• Stone Replication Technology: Utilizing multi-color fluorocarbon transfer printing, we ensure a texture repetition rate lower than $1/10,000 m^2$, accurately simulating the organic, random textures of natural marble.
• UV Resistance: After 4,000 hours of QUV accelerated weathering tests, the gloss retention remains $ge 80%$, ensuring the facade maintains a color deviation of $Delta E le 5$ over a 20-year lifespan.
