Order this productSPC (stone plastic composite) vinyl flooring combines a rigid core of limestone and stabilizers with a wear layer and a printed design film. The core provides dimensional stability under temperature fluctuations, while the wear layer protects against abrasion and staining. This construction yields a floor that resists water infiltration and maintains flatness in humid environments.
A typical SPC click vinyl plank consists of four layers: a UV‑cured wear layer (0.2 mm to 0.5 mm thickness), a high‑resolution decorative film, a SPC core (approximately 4 mm to 6 mm thick) containing calcium carbonate and PVC, and a balanced backing layer that reduces cupping. The click system is milled into the core edges, allowing panels to lock without adhesives.
Key technical values are presented below; actual numbers vary with formulation and are confirmed per project.
| Property | Typical Range | Test Method |
|---|---|---|
| Wear layer thickness | 0.2 mm – 0.5 mm | ISO 10582 |
| Core density | 1.8 g/cm³ – 2.0 g/cm³ | ISO 1183 |
| Water absorption (24 h) | <0.05 % | ASTM D570 |
| Dimensional change (heat) | <0.15 % | ISO 23999 |
| Click lock tensile strength | ≥1.5 kN/m | EN 424 |

The click system enables floating installation over a clean, level subfloor. Panels are angled and pressed together, engaging the milled tongue and groove. No glue or nails are required, which reduces installation time and allows for easy disassembly if reconfiguration is needed. A 2 mm expansion gap around the perimeter accommodates thermal movement.
Because the SPC core is impervious to water, the flooring suits areas where moisture exposure is frequent, such as food processing wash‑down zones, pharmaceutical cleanrooms, and locker rooms. The wear layer’s resistance to chemical spills and the low VOC emission profile make it appropriate for laboratories and electronics assembly areas where cleanliness is critical.
Each production lot undergoes inline thickness monitoring, wear layer abrasion testing (Taber ASTM D4060), and lock strength verification. Finished boards are inspected for color consistency, surface defects, and dimensional tolerance before packaging. Documentation of test results is available upon request.
Buyers can specify wear layer thickness, embossing pattern, bevel edge profile, and overall plank dimensions. Core formulation can be adjusted for increased impact resistance or enhanced acoustic performance. Color matching to corporate standards is achievable through the decorative film.
Boards are stacked in cartons with edge protectors and shrink‑wrapped to prevent moisture ingress during transit. Each carton label includes product code, batch number, and QR code linking to the test certificate. Palletized shipments comply with ISPM‑15 standards for international freight.
