An authoritative guide to understanding Stone Plastic Composite cladding, its physical attributes, performance optimization, and global commercial applications.
The SPC core composition leverages up to 70% calcium carbonate (CaCO₃) bound with high-molecular-grade PVC polymer, resulting in extremely high density and exceptional impact resistance.
Zero fiber content ensures a linear expansion coefficient near zero under constant humidity fluctuation, making it immune to damp environments, mold, and rot.
Featuring precision-milled micro-bevel click-lock edges (e.g., Unilin or Valinge-derived joints) that establish water-tight seals without requiring visible adhesive joints or trim rails.
How our multi-layered engineering protects against moisture, thermal wear, and chemical decomposition.
| Layer Name | Thickness / Configuration | Material Matrix | Engineering Purpose |
|---|---|---|---|
| 1. UV Guard Shield | Dual-cured PU coating | Urethane-acrylate cross-linked polymer | Protects against UV degradation, prevents fading, and provides antibacterial properties for hospital-grade installations. |
| 2. HD wear Layer | 0.3mm to 0.7mm | High-purity crystalline PVC polymer | Provides scratch resistance, impact buffer, and stain protection in high-traffic commercial spaces. |
| 3. HD Decorative Film | 4-Color Rotogravure Printing | Polyester pigment matrix | Replicates natural stone, hardwood grains, and custom geometric textures with high visual accuracy. |
| 4. Rigid SPC Core | 3.0mm to 6.0mm | CaCO₃ (Calcium Carbonate) + PVC resin (70:30 ratio) | Provides structural strength, zero water absorption, and Class B1 fire performance. |
| 5. Back Cushion (Optional) | 1.0mm - 1.5mm (IXPE or EVA) | Cross-linked closed-cell polyethylene | Improves acoustic insulation, dampens sound transmission, and accommodates minor subfloor or sub-wall unevenness. |

From coastal humidity to cleanroom sanitation, SPC offers robust properties for diverse projects.
In humid coastal regions, standard wood-based and gypsum-board panels face moisture damage and mold growth. Our SPC panels provide a 100% waterproof solution, making them ideal for coastal resorts and high-moisture spaces.
Hospitals and clinics require wall surfaces that resist microbial growth. The non-porous structure and polyurethane UV treatment of our SPC cladding prevent bacteria and mold from gathering, and can handle strong chemical disinfectants.
Busy locations like airports, subways, and commercial malls need high-strength surfaces. Our 0.7mm wear-layer SPC panels resist heavy impacts and scratches while maintaining their finish over long periods.
Explore our specialized systems, combining core panels with structural components to meet performance requirements.
How our manufacturing cluster integration and Northern China shipping hubs guarantee project timelines.
Our proximity to major limestone quarrying and polymer formulation facilities in Northern China reduces initial logistics costs and guarantees a steady supply of high-grade CaCO₃.
Our partner facilities utilize automated twin-screw extrusion systems that carefully control temperature and raw material ratios, ensuring consistent physical characteristics across every production batch.
Direct connections to Tangshan and Tianjin ports allow for rapid loading and shipping. This helps minimize sea transit times and reduces inland transportation costs for international shipments.
Adapting to evolving environmental standards, automated manufacturing, and smart product designs.
Developing protective coatings from agricultural by-products to replace petroleum resins, helping reduce the total carbon footprint of our panels.
Adopting high-speed digital printing that prints custom patterns directly onto the SPC core, removing the need for separate print films and decreasing waste.
Creating programs to process scrap SPC material back into core production. This recycled content helps reduce landfill waste without affecting panel performance.
Our materials comply with international safety, fire-resistance, and environmental standards.
