| Comparison Dimension | Sand-filled Turf | Fill-free Turf |
|---|---|---|
| Structural Design | High-density grass filaments (33,000-52,500 tufts/m²), bottom layer filled with quartz sand + rubber granules | High-pound curved filaments (grass height 13-15mm), double-density weaving for self-support |
| Compressive Performance | Compressive strength 40% higher than ordinary turf, suitable for high-intensity sports | No filler support, prone to collapse under long-term load |
| Cushioning Performance | Rubber granules enhance cushioning by 35%, reducing sports injuries | Cushioning depends on filament elasticity, slightly inferior to sand-filled type |
| Service Life | 8-12 years (fillers delay filament wear and aging) | 6-10 years (filaments bear wear directly, shorter lifespan) |
| Maintenance Cost | Regular filler replenishment required (about 28kg quartz sand + 4-7kg rubber granules per m²), maintenance frequency increases in arid areas | Only routine cleaning needed, low maintenance cost |
| Climatic Factor | Adaptability of Sand-filled Turf | Adaptability of Fill-free Turf |
|---|---|---|
| Strong UV/Temperature Difference | Quartz sand and rubber granules block partial UV rays, delaying filament aging; structural stability is less affected by temperature difference | Poor-quality materials are prone to brittleness and fracture under UV radiation, requiring UV-resistant materials (e.g., PE + UV stabilizers) |
| Low Winter Temperature | Rubber granules harden at low temperatures, affecting foot feel and sports experience | Self-supporting structure has strong cold resistance, filaments 不易 deform at low temperatures |
| Sandstorm Erosion | Sand particles are easily blown away by sandstorms, requiring quarterly filler replenishment with high maintenance costs | No fillers, sandstorms hardly damage the structure, significantly better sandstorm resistance than sand-filled type |
| Water Resource Consumption | No frequent watering needed (fillers maintain structural stability) | Some products require regular water spraying for dust control, water-saving design needed in arid areas |
