4.1 Fiber friction and contact stability
A rugby surface must generate enough friction for movement control, but not excessive “stickiness.” Vivaturf’s fiber friction range of 0.83–0.88 is positioned to sit within a controlled traction window suitable for rugby union movement demands.
4.2 Stability after repeated use
After 20,000 high-frequency loading cycles, the reference traction-decay rate in your source is ≤6%, compared with a premium-market reference of ≤10%. This suggests good stability under repeated training and match use.
4.3 Moisture and temperature consistency
Your source references:
- traction deviation across 30%–80% humidity: ≤0.03
- traction retention in −15°C to +65°C conditions: ≥95%
- wet-condition friction coefficient under simulated rainfall: ≥0.75
These values indicate a surface designed to maintain a more consistent grip profile across varying climates and weather conditions.
