3. Core Sports Performance Indicators
| Item | Technical Index |
|---|---|
| Ball rebound rate | ≥90% |
| Shock absorption | 20%–53% |
| Coefficient of sliding friction | 0.50–0.70 (safe anti-slip for sports) |
| Vertical deformation | ≥2.3 mm |
| Rolling load resistance | ≥2500 N, no crack or permanent deformation |
4. Physical & Weather Resistance
Operating temperature range: -40 ℃ ~ +70 ℃
Waterproof performance: 100% waterproof, hollow suspended design for rapid drainage
UV aging resistance: Stable color, no brittle cracking under long outdoor sunlight exposure
Impact resistance: No breakage after 1m free fall impact test
Expansion requirement: Reserve 5–10 mm expansion gap around the venue to adapt thermal expansion & contraction
5. Structure & Construction Parameters
Suspended clearance from base ground: 10–15 mm
Support structure: Dense column support feet (600–960 supporting points per tile)
Substrate requirement: Concrete/asphalt base, flatness deviation ≤3 mm within 2 m; drainage gradient ≥3‰ for outdoor sites
Expansion joint: Large-area venues need intermediate expansion joints when length exceeds 25 m
6. Service Life & Application
Service life: ≥8 years (outdoor); ≥10 years (indoor)
Applicable scenarios: Basketball court, badminton court, tennis court, futsal, playground, multi-function sports field, fitness area
7. Available Accessories
