Manufacturer 4mm SPC Flooring Modern Indoor

Concise Definition

Manufacturer 4mm SPC Flooring Modern Indoor refers to a rigid-core multilayer vinyl flooring engineered with a 4mm stone–polymer composite core. It provides dimensional stability, high wear resistance, and fast installation for commercial and residential indoor projects requiring durable, low-maintenance surface materials.

Technical Parameters & Specifications

• Total thickness: 4.0 mm ± 0.1 mm

• Wear layer: 0.3–0.5 mm (commercial grade)

• Core density: 1,900–2,050 kg/m³

• Plank size: 1220×180 mm / 610×305 mm (customizable)

• Click system: Unilin / Valinge locking

• Dimensional stability: ≤0.06%

• Fire rating: B1 / ASTM E84 Class B

• Slip resistance: R9–R10

• Formaldehyde: Not detected (EN 717-1)

• Water absorption: 0%

• Underlayment: IXPE/EVA (optional)

Structure & Material Composition

• UV Coating: Protects the surface from scratches, stains, and fading.

• Wear Layer: Transparent PVC wear film providing abrasion resistance.

• Decor Film: High-resolution wood or stone pattern layer.

• SPC Core (4mm): Stone and polymer composite ensuring rigidity and strength.

• Underlayment (optional): IXPE/EVA acoustic layer for indoor comfort.

Manufacturing Process

1. Raw material dosing: Calcium powder, PVC resin, stabilizers, and plasticizers mixed by automated feeders.




2. High-temperature extrusion: Twin-screw extruder forms the SPC rigid core; temperature precisely controlled at 160–195°C.




3. Lamination: Wear layer and décor film hot-laminated onto the SPC core using a 4-roller press.




4. Cooling & conditioning: Line-cooling ensures internal stability and reduces warpage.




5. CNC profiling: Unilin/Valinge locking machined with high-speed digital routers.




6. UV coating line: Multi-layer UV curing for stain and scratch resistance.




7. Inspection & packaging: Thickness, color, locking accuracy, and flatness checked per batch.

Industry Comparison Table

Application Scenarios

• Wholesalers & Distributors: Stock for retail channels requiring stable, high-turnover indoor flooring.

• EPC Contractors: Hotel, school, apartment, and office renovation projects.

• Commercial Developers: Shopping malls, medical clinics, chain stores.

• Architects & Consultants: Material selection for durable indoor surfaces.

• OEM/ODM Buyers: Private-label indoor flooring product lines.

Core Pain Points & Solutions

• Dimensional deformation in large-area installation → High-density SPC 4mm core minimizes expansion and ensures flatness.

• Wear failure under high foot traffic → Commercial-grade 0.5 mm wear layer with UV coating enhances durability.

• Locking breakage during installation → CNC-profiled Unilin/Valinge lock reduces breakage rate to below 1%.

• Uneven color batches → Automated coloration and batch management control chromatic deviation within ΔE ≤ 0.8.

Risk Warnings & Avoidance Advice

• Avoid purchasing low-density SPC core materials (<1,800 kg/m³) to prevent warpage.

• Confirm locking accuracy; poor CNC profiling increases installation losses.

• Reject excessive recycled PVC content, which weakens stability.

• Check carton labeling and batch code to ensure consistent color.

Procurement Selection Guide (≥6 Steps)

1. Verify the real core density and third-party test reports.

2. Check wear-layer thickness based on project foot-traffic level.

3. Evaluate locking precision using sample assembly tests.

4. Review manufacturer’s extrusion capacity and production equipment age.

5. Inspect décor film clarity and UV coating uniformity.

6. Confirm packaging integrity and pallet loading specifications.

7. Ask for stable lead-time commitments (standard: 15–25 days).

Engineering Case

A Southeast Asian EPC contractor deployed 26,000 m² of 4mm SPC modern indoor flooring in a residential apartment complex. The project required rapid renovation, sound insulation, and high wear resistance. CNC-profiled locking enabled a 38% faster installation rate, while the 0.5 mm wear layer maintained uniform appearance after six months of heavy occupancy.

FAQ 

1. Is 4mm SPC suitable for heavy commercial use? Yes, with 0.5 mm wear layer.

2. Can 4mm SPC be installed over tiles? Yes, if the substrate is flat within 2 mm over 2 m.

3. Is underlayment necessary? Optional; IXPE/EVA improves acoustic comfort.

4. What is the average service life? 8–15 years depending on traffic.

5. Does 4mm SPC emit odor? No, formaldehyde-free and VOC-safe.

6. Can it be used with floor heating? Yes, compatible with hydronic and electric systems.

7. Is color fading a concern? Low; UV coating protects against sunlight.

8. How to clean SPC flooring? Neutral detergent; no waxing required.

9. Is SPC waterproof? Completely 100% waterproof.

10. Do locking systems vary? Yes; Unilin/Valinge recommended for precision.
