Below is a professionally structured presentation of the main performance parameters retained from your source text and expressed in internationally familiar technical language.
Abrasion resistance
- Abrasion index: 7,000 cycles
(ASTM D3884 reference framework in your source text)
This indicates a surface built for repeated high-friction exposure such as crawling, dragging, weighted foot traffic, and aggressive movement patterns.
Compression set resistance
- Permanent deformation after 70°C × 22 h compression test: ≤1.5%
This suggests that the shock-attenuation layer maintains structural recovery even after prolonged loading and thermal exposure.
Fiber tensile strength
- Tensile strength: ≥150 N
This level supports resistance to breakage under aggressive training loads and repeated mechanical stress.
Fiber pull-out resistance
- Pull-out force: ≥40 N
A high tuft-bind value is particularly important for drag drills, crawling drills, and repetitive traction loading, helping prevent fiber loss over time.
UV weathering resistance
- UV aging resistance: 7,000 hours
- Color change after exposure: ΔE ≤2.5
These values indicate strong outdoor weathering stability for long-term exposure.
Thermal performance range
- Operational performance stability: -20°C to 70°C
- Performance loss under extreme temperatures: ≤5%
This makes the system suitable for both cold-weather and high-heat environments.
Shock absorption
- Shock absorption: 45%–60%
This range is well suited to high-load training applications where lower-limb protection is critical, especially under weighted movement and repeated landing.
Vertical deformation
- Vertical deformation: 6–9 mm
This provides a balance between:
- cushioning for impact reduction
- support for explosive movement efficiency
Slip resistance
- Dry friction coefficient: 0.65–0.85
- Wet friction coefficient: ≥0.55
These values support stable footing across both dry and wet conditions without creating an overly “sticky” surface that may interfere with rapid movement mechanics.
Environmental safety
- Heavy metal migration: ≤0.3 mg/kg
- TVOC emissions: ≤0.22 mg/(m³·h)
- Formaldehyde, benzene, toluene: not detected
These parameters support use in settings where both athlete health and environmental compliance matter.
