Performance remains the core dimension in the comparison between non-infill turf and natural grass. Natural grass is valued for its organic cushioning and tactile authenticity, while non-infill turf prioritizes consistency, durability, and adaptability across diverse environments.
Natural grass typically delivers a friction coefficient in the range of 0.6–0.8, closely aligned with human biomechanics, offering natural shock absorption and comfort. Its permeability relies on soil structure, with drainage rates generally around 5–7 L/(m²·min), allowing rainwater to dissipate effectively. However, natural grass performance is highly sensitive to climate and maintenance conditions. Exposure to temperatures below 5°C or above 35°C can lead to dormancy or degradation, resulting in seasonal performance variability and an annual dormancy period of approximately three to four months. Daily usage is usually limited to around four hours, as prolonged high-intensity use often leads to turf thinning and soil exposure, with recovery cycles ranging from 15 to 30 days.
Non-infill turf systems are engineered for stability and year-round usability. Typical non-infill fibers range between 6,000 and 10,000 Dtex, with tensile strength exceeding 30 N per fiber and elongation at break above 35%. Initial rebound performance commonly exceeds 90%, remaining above 80% even after extensive cyclic impact testing. Friction coefficients are controlled within 0.65–0.85, accommodating a wide range of sports requirements. Drainage performance often exceeds 6 L/(m²·min), with premium systems achieving rates above 8 L/(m²·min). Daily usage capacity can reach 8–12 hours, with service life commonly extending to 6–8 years. While some conventional non-infill systems may exhibit differences in tactile feedback compared with natural grass, advanced designs have significantly narrowed this gap.
