Renlong Flexible Stone Wall Panel
As a sustainable new choice for exterior wall decoration, this product is a novel eco-friendly decorative material manufactured from inorganic raw materials such as urban construction waste soil, cement residues, porcelain slag, and stone powder, through composite modification using polymer-based polymers. It combines the texture of natural materials with the flexibility of polymer-based materials, making it a popular exterior wall finishing solution for replacing natural stone.
Ingredients and Process
The raw materials for MCM Flexible Stone consist of three components: a base inorganic filler (such as waste soil, stone powder, etc.), a polymer modifier (water-soluble polymer emulsion), and functional additives (e.g., antifreeze agents, mineral pigments).
The preparation process comprises five major stages: raw material pretreatment, composite modification, photo-induced isomerization, compression molding curing, and surface treatment. The photo-induced isomerization reaction, which occurs under a controlled temperature profile, imparts excellent plasticity to the modified soil and constitutes the core of this process.
The entire production process is zero-emission and zero-pollution, with a unit energy consumption of only 20% of that required for traditional ceramics.
Core Performance
These flexible stone wall panels have a thickness of only 2–4 mm and a weight of 3–8 kg/m²; they can be bent through 180° on a 20 cm diameter cylinder without cracking. They pass weathering tests for over 2,000 hours and exhibit equivalent outdoor weather resistance that remains stable for 50 years.
Waterproofing performance: maintains no leakage under a water pressure of 0.3 MPa for 30 minutes; water absorption rate is approximately 6%; water vapor dry flux density reaches 0.95 g/(m²·h), achieving "water-repellent and breathable" properties.
Salt spray resistance: The material itself is resistant to acid, alkali, and salt corrosion; when supplemented with polymer-based synergistic protection, it remains free of bubbling or peeling after immersion in 3% hydrochloric acid or a 30 g/L potassium hydroxide solution for 800 hours, making it suitable for coastal and industrial environments.
Freeze-thaw resistance: The product withstands 100 repeated freeze-thaw cycles across the temperature range from –30°C to 10°C; it exhibits no surface powdery degradation, no cracks, and no peeling, equivalent to approximately 100 years of natural exposure.
Fire resistance performance: Due to the incorporation of a high concentration of inorganic flame-retardant components, this material achieves a Class A fire rating (non-combustible material), meeting the fire protection requirements for exterior walls of high-rise buildings. Additionally, its stain resistance rating reaches Level 4, and it features a nano-self-cleaning function.
Advantages over natural stone
Eco-friendly: Utilizes waste soil as raw material, is recyclable, avoids mountain excavation for stone mining, and achieves an energy efficiency rate exceeding 80%.
Easy installation: weighing only one-tenth of that of stone; requires no anchoring for direct adhesive application and can conform to irregularly shaped curved surfaces.
System Safety: The flexible material's properties harmonize with the thermal insulation layer, effectively resisting cracking and detachment; its Class A fire resistance rating surpasses that of stone dry-hanging systems.
Controllable aesthetics: featuring 256 natural color shades; the mold cloning technology replicates textures such as stone and wood patterns, ensuring batch-to-batch consistency that far surpasses that of natural stone.
Cost advantage: The integrated structure reduces workload, improves construction efficiency, and lowers maintenance costs; consequently, the total life-cycle cost is significantly lower than that of natural stone.
Against the backdrop of the "Dual Carbon" strategy and the upgrading of green building standards, Renlong flexible stone panels are pioneering a new path toward sustainable materials in the exterior wall decoration sector through their eco-friendly attributes and exceptional performance.
Renlong is the inventors and leading manufacturer of flexible stone wall panels in China. After years of research and preparation, we began production and launched our first generation product to the market in 2008. Having gone through countless classic cases and learned too many experiences and lessons, we have achieved the excellent quality of today's Renlong flexible stone wall panels along the way. Our flexible stone wall panels is mainly composed of inorganic powder and modified clay as raw materials, accounting for 98%. Specific gravity: 1.2 Waterproof Fireproof (class A 1) Salt spray resistance Freeze thaw resistance Can be used outdoors for more than 30 years. It can be slightly bent, so it is also known as flexible stone. We can replicate the delicate textures and typical features of various natural stones, and use patented inorganic powder 3D printing technology to ensure that outdoor use will not fade due to sunlight exposure and wind and rain erosion. Renlong flexible stone wall panels adopts wet pasting technology and can be easily installed with tile adhesive. Compared with the traditional wall dry hanging stone craftsmanship, Save 75% on main and auxiliary materials and labor costs Save 50% of construction time Save 40% on material transportation and handling costs.
