Below is a polished English presentation of the technical values retained from your article and expressed in a more internationally familiar format.
Shock absorption
- 40%–55%
This range is well above the baseline commonly referenced for general-purpose sports surfaces and provides a balanced level of cushioning for both:
- higher-load activities such as football and basketball
- lower-load recreational or fitness use
Vertical deformation
- 5–8 mm
This range helps balance:
- underfoot comfort
- force return
- movement stability
It prevents the surface from feeling overly hard for general users while avoiding the excessive softness that can interfere with performance-oriented movement.
Ball rebound
- ≥90%
This supports multi-sport functionality, especially for activities where predictable ball response is important. It allows the surface to remain relevant not only for football-style play but also for broader recreational ball-sport use in indoor halls.
Anti-static performance
- Surface resistivity: 10^6 to 10^9 Ω
This range is suitable for reducing static build-up in enclosed indoor facilities and helps limit dust adhesion to the surface.
Noise reduction
- Impact sound reduction: ≥15 dB
This is a meaningful performance feature for indoor arenas, especially where multiple programs operate in neighboring spaces or where acoustic comfort affects perceived venue quality.
VOC / indoor air quality
- TVOC emissions: ≤0.18 mg/(m³·h)
- Odor rating: ≤3.0
- Heavy metal migration: ≤0.3 mg/kg
- Formaldehyde, benzene, toluene: not detected
These values support a healthier indoor environment, where low odor and low emissions are especially important.
Abrasion resistance
- Abrasion index: 6,500 cycles
(ASTM D3884 reference in your source text)
This level supports long-term use in busy indoor venues subject to repeated daily traffic and mixed programming.
Hydrophobic stain resistance
- Water contact angle: ≥90°
This contributes to easier cleaning and better short-term stain resistance for beverage spills and daily usage marks.
Fiber pull-out resistance
- Pull-out force: ≥35 N
A high tuft-bind value helps maintain long-term surface integrity even during deep cleaning or repeated movement stress.
Friction / traction
- Dry friction coefficient: 0.60–0.80
- Wet friction coefficient: ≥0.50
These values support safe movement both in normal dry operation and after cleaning or incidental moisture exposure.
