Below are the core technical indicators most relevant to low-temperature recreation areas. The values have been presented in a format more familiar to European and North American technical readers.
Low-Temperature Stability
For snow venue applications, the turf system must retain its properties under extended cold exposure. Vivaturf systems are engineered for service in a temperature range of approximately -30°C to 50°C. After repeated freeze-thaw cycling, impact absorption and vertical deformation are designed to remain within controlled variation bands, helping the surface maintain consistent performance over time.
Wet Slip Resistance
Wet traction is essential where meltwater is regularly present.
- Dry coefficient of friction: approximately 0.60-0.80
- Wet coefficient of friction: ≥0.55
This range supports stable pedestrian movement and light recreational activity while avoiding an overly aggressive surface feel.
Moisture Resistance and Mold Control
The closed-cell cushion structure is designed for:
- Water absorption: ≤0.1%
- Mold resistance: Grade 0
These values help reduce the risk of odor, biological growth, and structural degradation in damp environments.
UV Durability in Snow-Reflective Environments
Snow and ice amplify UV exposure through reflectivity. For that reason, UV stability remains important even in cold climates.
- UV resistance: up to 7000 hours
- Color change: ΔE ≤2.5
This helps preserve appearance and fiber integrity in exposed alpine or snow park applications.
Low-Temperature Fiber Toughness
At low temperatures, many conventional fibers lose flexibility. Vivaturf cold-climate systems are engineered to maintain toughness in subzero conditions, helping prevent cracking or brittle failure during winter use.
Compression and Cushion Stability
The cushion layer is engineered to resist permanent deformation:
- Permanent deformation after thermal compression testing: ≤2%
That helps maintain consistent shock absorption and footfeel even after prolonged service.
Hydrophobic Surface Behavior and Drainage
For snowmelt recovery, the surface must shed water quickly.
- Water contact angle: ≥95°
- rapid runoff through fiber spacing and underlying drainage design
This helps reduce standing water and shortens the time required for the area to return to service.
Environmental Safety
For public-facing recreation areas, chemical safety is also important.
- Heavy metal migration: ≤0.3 mg/kg
- TVOC emission: ≤0.22 mg/m³·h
- no detectable formaldehyde, benzene, or toluene in standard testing conditions
- Odor rating: ≤2.5
These indicators support use in family-oriented and enclosed-adjacent environments.
