Climate-controlled venues demand consistency over time rather than just initial performance. The parameter framework in your article reflects this requirement.
Performance stability under controlled conditions
- Test condition: 25°C / 60% humidity / 1000 hours simulation
- Shock absorption decay: ≤3%
- Vertical deformation decay: ≤2%
This indicates relatively stable mechanical behavior over long-term indoor use.
Moisture resistance
- Closed-cell ratio: ≥98%
- Water absorption: ≤0.1%
Helps prevent moisture-related degradation and microbial issues.
Anti-static performance
- Surface resistivity: 10⁶–10⁹ Ω
This range aligns with indoor sports surface requirements, reducing dust accumulation and improving cleanliness.
Air quality and emissions
- TVOC: ≤0.18 mg/(m³·h)
- Odor rating: ≤2.5
- Heavy metals: ≤0.3 mg/kg
- No detectable formaldehyde, benzene, or toluene
These values are particularly important for enclosed venues where ventilation is limited.
Durability and cleanability
- Wear resistance: ~6,500 cycles (ASTM D3884)
- Fiber pull-out strength: ≥35 N
- Water contact angle: ≥90° (hydrophobic surface)
This combination supports:
- resistance to intensive use
- easy cleaning of spills or contaminants
- long-term surface integrity
Slip resistance
- Dry: 0.60–0.80
- Wet (post-cleaning): ≥0.50
Ensures safe traction even after maintenance or cleaning cycles.
