Technical Parameters Buyers Should Review

Instead of only comparing grass height and density, buyers should ask for performance data that reflects real field quality.

Recommended evaluation indicators include:

Wear resistance:
Vivaturf reference value: up to 6,500 cycles under ASTM D3884
This helps indicate resistance to repeated foot traffic and surface abrasion.

Yarn tensile strength:
Vivaturf reference value: ≥120 N
This helps reduce yarn breakage and surface degradation.

Yarn pull-out force:
Vivaturf reference value: ≥35 N
This reflects how firmly the yarn is anchored into the backing.

Shock absorption:
Vivaturf reference range: 40%–55%
This supports user comfort and joint protection.

Vertical deformation:
Vivaturf reference range: 5–8 mm
This helps balance cushioning and stable foot support.

UV aging resistance:
Vivaturf reference value: up to 6,000 hours
This supports outdoor color and mechanical stability.

Hydrolysis resistance:
Vivaturf backing strength retention: ≥95% after 1,000 hours accelerated hydrolysis testing
This is especially important in humid, rainy, or indoor high-humidity environments.

Environmental safety:

• Heavy metal migration: ≤0.3 mg/kg
• TVOC emission: ≤0.22 mg/(m³·h)
• Formaldehyde and benzene-related substances: not detected under relevant test conditions

These values are far more meaningful than pile height alone.

8. Installation and Quality Control Are Also Part of the Product

A good non-infill turf system also needs professional installation and field acceptance testing. Even a high-quality product can underperform if the base is uneven, the seams are poorly bonded, or the drainage design is incorrect.

Vivaturf recommends full-process quality control:

• Base flatness controlled within ≤3 mm over 3 m
• Base strength of C25 or above, depending on project requirements
• Verified third-party test reports before installation
• Controlled seam bonding and edge fixing
• On-site testing for shock absorption, vertical deformation, friction, drainage, and environmental safety where required

This system-based approach helps ensure that laboratory performance can be translated into real field performance.

Many buyers focus on the visible grass layer and ignore the cushion system underneath. This is a major mistake.

For non-infill turf, the cushion layer plays a key role in shock absorption, vertical deformation, rebound, player comfort, and long-term surface stability. If the cushion layer is missing, too soft, too hard, or made from low-grade recycled foam, the field may become uncomfortable or unstable after use.

Vivaturf can be paired with a custom closed-cell PE shockpad system, engineered for stable cushioning and support.

Common performance targets include:

• Shock absorption: 40%–55%
• Vertical deformation: 5–8 mm
• Closed-cell structure: helps resist water absorption and compression collapse
• Compression set after 70°C × 22 h testing: ≤2%

This helps the field avoid the two common problems of poor non-infill products: being too hard and unsafe, or too soft and unstable.

Bonding Technology Affects Long-Term Stability

Traditional adhesive bonding can be a weak point in turf systems. Under moisture, heat, and long-term use, low-grade adhesives may age, hydrolyze, or lose bonding strength, leading to backing separation or cushion-layer failure.

Vivaturf emphasizes a more stable structural bonding approach, including thermal bonding and low-odor, environmentally controlled bonding systems, depending on the project design. This helps reduce odor, improve layer stability, and support long-term field performance.

For buyers, the key is not only whether the grass looks dense, but whether the entire system can remain integrated after years of use.

Pile height and density are basic appearance parameters. They can tell you how the turf looks, but they cannot fully explain how the field will perform under real use.

Some low-quality non-infill turf products are intentionally made with taller yarns and higher density to look premium. However, the manufacturer may cut costs on the fiber resin, backing, cushion layer, or bonding process. These products may look attractive at first, but after a short period of use, they can develop common problems such as fiber wear, matting, yarn breakage, backing delamination, poor drainage, and unstable cushioning.

For non-infill turf, this problem is even more important because the system does not use sand or rubber infill to help support the yarn. The turf itself must provide the support, cushioning, rebound, and long-term structural stability.

That means buyers should look deeper than pile height and density.

Fiber Material Matters More Than Pile Height

The quality of the yarn material is one of the most important factors behind turf lifespan. Low-cost turf may use recycled plastic or poorly modified resin, which can lead to weak tensile strength, poor UV resistance, brittleness, faster fading, and early fiber breakdown.

Vivaturf non-infill turf uses engineered polymer yarn systems designed for durability, resilience, and outdoor stability. The yarn formulation can include wear-resistant, UV-resistant, anti-static, and weather-resistant additives to help maintain fiber performance over time.

Key reference indicators include:

• Yarn wear resistance: up to 6,500 cycles under ASTM D3884 reference testing
• Yarn tensile strength: ≥120 N
• UV aging resistance: up to 6,000 hours accelerated UV aging
• Post-aging performance retention: designed to remain stable under long-term outdoor exposure

A turf product with moderate pile height but stronger yarn chemistry can often perform better than a taller product made from weaker material.

When selecting non-infill artificial turf, many buyers focus only on two visible numbers: pile height and stitch density. A taller pile and higher density may look impressive on a specification sheet, but they do not necessarily indicate better performance.

For non-infill turf, the real performance depends on a complete system: fiber material, fiber structure, backing stability, shockpad design, bonding technology, environmental safety, and long-term durability. A product with high pile height and high density can still fail quickly if the yarn is made from low-grade recycled material, the backing is weak, or the cushion layer collapses after use.

This is why Vivaturf approaches non-infill turf as an engineered sports surface system rather than a simple “tall and dense grass” product. For buyers in Europe, North America, and other global markets, this system-based approach offers a more reliable way to evaluate quality, long-term value, and field performance.

A high-performance turf system must be supported by proper installation. Vivaturf uses different quality-control priorities depending on whether the field is designed for matches or training.

Match Field Installation Priorities

For match fields, installation precision is critical. The base should be highly level, with flatness commonly controlled within ≤2 mm over 3 m where the project specification requires it. This helps reduce ball roll deviation and supports consistent playability.

During acceptance testing, key checks may include:

• Ball rebound
• Ball roll
• Shock absorption
• Vertical deformation
• Friction coefficient
• Seam flatness
• Surface uniformity
• TVOC and odor performance for indoor applications

Training Field Installation Priorities

For training fields, structural strength and long-term durability are more important. The base may require higher load-bearing capacity, often C30 or above depending on project design, especially for high-intensity training areas.

Acceptance testing may focus on:

• Wear resistance
• Yarn pull-out force
• Compression set
• Shock absorption
• Vertical deformation
• Seam bonding strength
• Drainage and moisture resistance
• UV and aging test documentation

This differentiated installation logic helps ensure that the turf performs according to the real use scenario, rather than applying one generic standard to every field.
