2.1 Yarn Material: Virgin Modified Polymer vs. Recycled Low-Grade Plastic
Low-cost non-infill turf often uses recycled plastic or low-grade raw materials to reduce cost. These materials may contain impurities and typically have weaker mechanical performance. Without proper modification, the fibers may become brittle, flatten, fade, or break after limited use.
Professional non-infill turf uses higher-grade virgin polymer materials, often with performance-enhancing additives for wear resistance, UV stability, antistatic behavior, and weather resistance. This increases material cost, but it also improves long-term durability.
Vivaturf uses modified polymer yarns engineered for outdoor sports and high-frequency use. This helps the turf maintain fiber strength, resilience, and color stability over time.
2.2 Yarn Structure: Single Yarn vs. Straight-and-Curled Biomimetic Matrix
Many low-cost non-infill products use a single stiff yarn structure. This is an inexpensive way to make the grass stand up without infill, but it often creates a hard, uncomfortable surface with limited cushioning. If the yarn is too soft, the field may collapse quickly; if it is too hard, the field may feel harsh and increase impact stress.
Vivaturf uses a straight-and-curled biomimetic yarn matrix, commonly engineered around a 7:3 straight-to-curled ratio. The straight fibers provide support and upright stability, while the curled fibers help improve cushioning, rebound, and foot comfort. This structure is more complex and more expensive to manufacture, but it helps balance support and protection more effectively.
2.3 Backing System: Single-Layer Glue Backing vs. Reinforced Composite Backing
The backing system is one of the most important cost drivers in non-infill turf. Low-cost products often use thin, single-layer backing with conventional adhesive bonding. Over time, moisture, heat, and mechanical stress may cause hydrolysis, delamination, cracking, or yarn loss.
Professional non-infill turf requires a stronger backing because there is no infill to help stabilize the turf structure. Vivaturf uses a reinforced multi-layer backing system with high-strength structural support. This improves yarn anchoring, dimensional stability, and long-term durability.
Vivaturf’s yarn pull-out force can reach ≥35 N, compared with around 10–15 N often seen in lower-grade products. This makes the turf much more resistant to fiber loss under repeated foot traffic, dragging, and sports use.
2.4 Cushioning Layer: Low-Grade Foam vs. Customized Closed-Cell Shockpad
Some low-cost non-infill turf products have no proper shockpad, or they use low-density recycled foam. These layers may collapse quickly, causing the field to become harder over time.
Vivaturf can be paired with a customized closed-cell PE shockpad, engineered for stable cushioning and long-term compression resistance. With a properly designed shockpad, the field can achieve a better balance between shock absorption and vertical deformation.
Typical Vivaturf performance ranges include:
Shock absorption: 40%–55%
Vertical deformation: 5–8 mm
Compression set after 70°C × 22h testing: ≤2%
These values help support athlete comfort, joint protection, and long-term field stability.
2.5 Additives and Processing: Basic Additives vs. Environmentally Controlled Nano-Level Dispersion
Low-cost turf may use poor-quality additives or insufficient UV stabilizers. This can lead to fading, brittleness, odor, and performance decline.
Professional turf systems use controlled additive packages, including UV stabilizers, wear-resistant modifiers, antistatic additives, and environmental safety additives. Vivaturf uses well-dispersed additives designed for long-term stability, helping reduce early aging, fading, and performance loss.
