To understand how infill affects playing performance, we compared two systems using the same turf model (MangoSports ProSport 40), one with SBR and the other with cork infill.
Test Metrics (based on EN 15330-1 standards):
| Parameter | SBR Infill | Cork Infill |
|---|---|---|
| Shock Absorption | 63% | 60% |
| Vertical Deformation | 9.0 mm | 8.2 mm |
| Ball Rebound | 1.0 m | 0.94 m |
| Rotational Resistance | Moderate | High |
| Surface Temperature | High (45°C+) | Low (30–35°C) |
This illustrates that while SBR infill offers slightly more bounce and lower cost, cork infill improves rotational grip and significantly lowers surface heat.
Environmental Impact of Infill Choices
Environmental considerations are becoming increasingly important in synthetic turf projects. Here’s how different materials compare:
- SBR and EPDM: Derived from petroleum and may release VOCs or microplastics over time.
- TPE: Recyclable and more stable, but still synthetic.
- Cork and BrockFILL: Biodegradable, renewable, and safer for stormwater systems.
If you’re pursuing LEED certification or wish to minimize ecological impact, natural infill options are more appropriate—though typically at a higher cost.
