Order this productRigid core SPC (stone plastic composite) vinyl flooring combines a calcium carbonate‑filled core with a wear layer and a printed decorative film. This structure provides high impact resistance, dimensional stability, and suitability for areas with temperature fluctuations.
The core typically contains 60% limestone powder, 30% polyvinyl chloride, and 10% plasticizers and stabilizers. This formulation yields a flexural modulus of approximately 3,500 MPa and a water absorption rate below 0.02% after 24 h immersion.
| Property | Typical Value | Test Method |
|---|---|---|
| Overall thickness | 4.0 mm – 6.0 mm | ISO 24346 |
| Wear layer thickness | 0.3 mm – 0.7 mm | ISO 24340 |
| Density | 1.9 g/cm³ – 2.1 g/cm³ | ISO 1183 |
| Thermal conductivity | 0.14 W/(m·K) | ISO 8302 |
| Fire rating | Bfl‑s1 (EN 13501‑1) | EN 13501‑1 |
Due to its low moisture absorption and resistance to chemical spills, rigid core SPC is commonly selected for warehouses, production lines, and automotive service bays where frequent cleaning and occasional oil exposure occur. The product’s click‑lock installation reduces downtime compared with glued‑down alternatives.
Each production batch undergoes inline thickness gauging, wear layer adhesion testing (peel strength ≥ 1.5 N/mm), and color consistency checks using spectrophotometry (ΔE ≤ 1.5). Final inspection includes a slip resistance test (R10 per DIN 51130) for safety‑critical zones.
Plants typically pack planks in cardboard cartons with corner protectors, then stack on Euro‑pallets (800 mm × 1200 mm). Each pallet holds approximately 500 mm² of flooring, allowing efficient container loading. Moisture‑barrier liners are included for overseas shipments to prevent core swelling.
