SPC Wall Panel

Core Differences:

Compared with carbon crystal panels (bamboo, wood and calcium powder composite), SPC panels have a higher proportion of stone powder, greater hardness and lower water absorption rate. Compared with engineered veneer panels, SPC panels are moisture-resistant. Compared with calcium silicate boards (inorganic cement boards), SPC panels are lighter in weight and come with finished decorative surfaces. Compared with full-aluminum honeycomb panels, SPC panels feature lower cost and eliminate metal resonance issues.

Multi-layer Composite Structure of the Panel

UV Wear-resistant Protective Layer: Nano UV coating, scratch-resistant, stain-resistant and anti-aging. It prevents yellowing and fading of the surface, and daily stains can be wiped off effortlessly.

High-definition Decorative Film Layer: Thermally laminated decorative film, replicating textures such as marble, wood grain, solid colors and fabric grain. It offers rich color options with no color difference.

Solid SPC Stone Crystal Substrate Layer: Solid board co-extruded at high temperature from stone powder and PVC, dense and non-hollow. With high hardness and low shrinkage, it serves as the core for the panel’s stability and waterproof performance.

Balancing Back Layer: Balancing film on the rear side to counteract internal stress of the panel and reduce deformation and arching caused by thermal expansion and cold contraction.

Production Process

Raw material proportioning (stone powder + PVC + stabilizer) → High-temperature extrusion to form integrated base panel → Surface dedusting and preheating → Thermal lamination of decorative film → Curing of UV wear-resistant coating → Constant-temperature conditioning for dimensional stabilization → Click profile milling (for click-lock type) → Precision cutting → Quality inspection for hardness, waterproof performance and color difference → Protective film covering → Packing and warehousing

Core Performance Features

✅ Key Advantages

Near-zero water absorption, waterproof and mildew-proof: The dense substrate does not absorb water. It can be used in bathrooms, kitchens and basements for a long time. It will not swell, crack or get mildewed when soaked in water.

Zero formaldehyde and low VOC: No adhesive is used during production, and no wood is contained in raw materials. Its environmental grade exceeds ENF standard. It is ready for occupancy right after installation, suitable for enclosed spaces.

High hardness, wear and impact resistance: The surface UV wear-resistant layer resists scratches. It can withstand frequent knocks in public areas and is acid & alkali resistant.

Excellent dimensional stability: Low thermal expansion and contraction coefficient. It hardly arches, shrinks or deforms under high or low temperatures, and remains stable during the south China humid returning spring season.

Dry rapid installation with short construction period: Mainly assembled via click-lock system, and can also be bonded with nail-free glue. No large-area leveling or demolition is required for old walls, ideal for old house renovation.

Rich patterns and styles: Marble, log, solid color and cement textures, compatible with modern, light luxury, minimalist and various decoration styles.

Relatively light weight, lighter than calcium silicate boards and natural stones, reducing bearing load on keels.

⚠️ Disadvantages

Fire rating B1 (difficult to ignite). It cannot reach Class A non-combustible standard, so it is not applicable for sites with mandatory Class A fire protection requirements.

The panel becomes brittle in low-temperature environments. Panels made of inferior recycled materials show more obvious brittleness and are prone to edge chipping under heavy impact during handling.

Due to plastic properties, it tends to age under long-term high-temperature sun exposure, and is not suitable for outdoor applications with continuous direct sunlight.

Poor bending performance. As a rigid panel, grooving on the back side is mandatory if curved shapes are needed. It cannot be bent directly at room temperature like flexible curved boards.

Average sound insulation performance. The solid substrate provides limited sound insulation, which cannot meet the professional noise reduction level of damping soundproof boards.

High risks for low-cost recycled-material products: panels made from recycled materials may contain excessive plasticizers and tend to turn yellow and become brittle after long-term service.

Key Points for Selection & Identification

Distinguish raw materials: Priority shall be given to brand-new virgin materials. Panels made from recycled materials are brittle with strong odor and prone to yellowing after long-term use.

Check cross-section: The cross-section shall be dense and uniform without holes or impurity particles. Inferior panels feature rough fracture surfaces and abundant air pores.

Inspection of UV wear-resistant layer: Intact surface UV coating, resistant to scratches in scratch resistance test.

Focus on milling profile for click-lock type: Tight interlock of click joints, narrow splicing gaps and low risk of loosening.

Select thickness as required: 5–6 mm for general residential decoration; 8 mm thick version for high-traffic commercial projects such as hospitals and hotels.

Tips for Foreign Export

SPC wall panels contain no wood, bamboo or other plant fibers. EUDR timber traceability is not required for exports to the EU, enabling simple customs clearance.

Export test items: B1 flame retardant test, formaldehyde & VOC test, abrasion resistance test, hot water immersion resistance test.

Overseas application scenarios: Overseas homestays, hotels, container interior decoration and renovation projects in humid areas.

Packaging: The rigid panels are vulnerable to edge chipping. Pack with corner protectors, protective film and pallets to avoid impact damage during transportation.

Key Installation Points

The wall surface should be as flat as possible. Large pits and depressions need pre-leveling. Click-lock wall panels have certain requirements on substrate flatness.

Reserve tiny expansion joints to cope with temperature changes and prevent arching.

For installation in wet areas of kitchens and bathrooms, seal panel seams with neutral mildew-proof sealant to further improve moisture resistance.

Not recommended for areas under long-term direct shower spray (special SPC waterproof wall panels with matched waterproof systems can be adopted).

Applicable Scenarios

✅ Recommended Use Scenarios

1. Home Decoration: Bathroom dry areas, kitchen backsplashes, basements, living room and bedroom wainscoting, old house renovation

2. Commercial Decoration: Hotel rooms, guesthouses, shops, hospital corridors, school public areas, clean rooms

3. Special Interior Decoration: Containers, modular cabins, RV interiors, and other damp and enclosed spaces

❌ Not Recommended Scenarios

Outdoors exposed to prolonged sunlight, public places requiring Class A fire resistance certification, projects requiring large-curvature surface designs.
