Order this productThis product line supplies rigid core planks manufactured from stone‑plastic composite (SPC) for high‑traffic commercial environments where dimensional stability and moisture resistance are critical performance criteria.
| Parameter | Typical Value | Test Standard |
|---|---|---|
| Overall Thickness | 5.5 mm (±0.1 mm) | ASTM F387 |
| Wear Layer Thickness | 0.55 mm (commercial grade) | ASTM F410 |
| Plank Width | 180 mm (customizable 100‑250 mm) | — |
| Plank Length | 1220 mm (customizable 600‑1800 mm) | — |
| Locking System | Uniclic®‑compatible click | — |
| Static Load Limit (PSI) | 250 psi (no permanent indentation) | ASTM F970 |
| Indentation Resistance | ≤0.05 mm after 750 psi load | ASTM F1914 |
| Dimensional Stability (ΔL/L) | ≤0.15 % after 8 h at 80 °C/80 % RH | ASTM F2199 |

The core consists of approximately 60 % calcium carbonate, 30 % polyvinyl chloride, and 10 % stabilizers and lubricants, producing a homogeneous matrix that eliminates plasticizer migration and provides a modulus of elasticity around 3.5 GPa.
A UV‑cured polyurethane top coat protects the wear layer, while a balanced backing layer ensures symmetrical construction to counteract curling.
In healthcare facilities the floor’s impermeable surface prevents fluid ingress, supporting infection control protocols without the need for sealants.
Retail environments benefit from the product’s high static load tolerance, allowing continuous operation of heavy shelving units and checkout counters over extended periods.
Educational institutions select SPC planks for classrooms and corridors because the low VOC emissions (≤50 µg/m³) meet indoor air quality standards while the acoustic underlay reduces impact noise by up to 18 dB.
Each production line incorporates inline laser thickness gauges that reject any plank deviating beyond ±0.1 mm from the target 5.5 mm.
Wear resistance is verified by Taber abrasion testing (CS‑10 wheels, 1000 cycles) with a target weight loss ≤0.02 g, confirming suitability for commercial traffic classifications.
Chemical resistance checks involve 24‑hour immersion in isopropyl alcohol, diesel, and bleach solutions; no surface delamination or discoloration is permitted.
Cartons are sized to hold 1.5 m² of flooring, each weighing approximately 18 kg, facilitating manual handling while optimizing container cube utilization.
Pallets accommodate 48 cartons (≈864 kg) and are secured with PET straps; a polyethylene liner guards against humidity during ocean transit.
Lead time for standard stock items is 10‑12 working days; customized runs require 18‑22 working days after final design approval.
Yes, width, length, wear layer thickness, and embossing can be tailored to project specifications; tooling adjustments are quoted separately.
Required details include total area, desired plank dimensions, wear layer grade, color reference, packaging preference, and delivery destination.
Every batch undergoes dimensional checks, wear layer abrasion, static load, and chemical resistance tests; a test report accompanies each shipment.
Standard packaging is corrugated cartons with shrink wrap; optional palletization with corner boards and moisture barrier film is available upon request.
Cartons are placed on fumigated pallets, wrapped in polyethylene, and secured with strapping; container loading follows ISO 1496‑1 guidelines for cargo safety.
Standard items ship within 10‑12 working days; customized orders typically require 18‑22 working days after final artwork confirmation.
Sample kits containing up to four planks are dispatched via express courier; charges are credited against the first purchase order.
