The following values are based on the parameter framework you provided, normalized into internationally readable technical language.
4.1 Wear and durability
Industry premium reference
- Lisport wear resistance: ≥12,000 cycles
- Fiber pull-out force: ≥4.0 N/mm
- Fiber breaking strength: ≥38 N
- Wear-performance decay after repeated loading: ≤9%
Vivaturf baseball outfield configuration
- Lisport wear resistance: ≥16,500 cycles
- Fiber pull-out force: ≥4.9 N/mm
- Fiber breaking strength: ≥46 N
- Wear-performance decay after repeated loading: ≤4%
These values indicate a surface engineered for longer-lasting structural integrity under repeated outfield use.
4.2 Ball response
Industry premium reference
- Vertical rebound rate: 38%–45%
- Rolling resistance coefficient: 0.75–0.85
- Rebound consistency deviation across 10 test points: ≤3%
Vivaturf baseball outfield configuration
- Vertical rebound rate: 41%–44%
- Rolling resistance coefficient: 0.79–0.83
- Rebound consistency deviation: ≤1.2%
This is particularly important in baseball, where reading the speed and direction of the ball is essential.
4.3 Traction and weather resistance
Industry premium reference
- Dry friction coefficient: 0.76–0.88
- Wet friction coefficient: ≥0.65
- UV aging retention after 5,000 h: ≥90%
- Temperature-performance retention: ≥88% in −25°C to +70°C
Vivaturf baseball outfield configuration
- Dry friction coefficient: 0.81–0.84
- Wet friction coefficient: ≥0.73
- UV aging strength retention: ≥95%
- Temperature-performance retention: ≥94% in −25°C to +70°C
These values support better all-weather usability and more reliable footing during outdoor play.
4.4 Drainage and outdoor usability
Vivaturf outfield reference
- Water permeability: ≥10 L/(m²·min)
- Surface recovery after heavy rain: typically around 20 minutes under correctly designed drainage conditions
This helps keep the outfield playable after rain while reducing the risk of water-related deterioration.
