Cushion Layer Determines the Real Field Feel

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.
