Key Technical Parameters for Youth Protection

Vivaturf non-infill turf is designed to align with commonly referenced sports-surface performance expectations in North American and European markets.

Shock absorption: approximately 40%–55%
This exceeds the commonly referenced ≥35% baseline and helps reduce landing impact on developing joints.

Vertical deformation: approximately 5–8 mm
This range balances cushioning and stability, providing a more natural underfoot feel without excessive softness.

Friction performance:
Dry condition: 0.60–0.80
Wet condition: ≥0.50
This helps support traction during running and turning while reducing the risk of excessive grip that may increase ankle stress.

Fiber pull-out force: ≥35 N
Stronger fiber anchoring helps reduce fiber loss and lowers the risk of children pulling out fibers during play.

Abrasion resistance: 6500 cycles under ASTM D3884 reference testing
This supports long-term use in high-frequency youth sports environments.

UV aging resistance: 6000 hours
Designed for outdoor use with improved resistance to fading, brittleness, and performance decline.

Upright fiber retention after repeated use: ≥95%
This helps the surface maintain consistent cushioning, traction, and appearance over time.

Environmental safety indicators:
Heavy metal migration: ≤0.3 mg/kg
TVOC emission: ≤0.22 mg/(m³·h)
Formaldehyde, benzene, and toluene: not detected

These parameters support healthier use in school and youth sports environments.
