To judge the quality of artificial turf, a comprehensive examination of raw materials, physical properties, environmental protection standards and professional test reports is required, with particular attention paid to the material of grass fibers, the structure of the base and back, durability and safety indicators.
Youdaoplaceholder0 Core quality indicators
Youdaoplaceholder0 grass filament material and process .
Made of new high-purity PP/PE raw materials, the grass fibers have neat cuts without burrs, uniform color and are resistant to ultraviolet fading.
High-quality grass fibers are soft and resilient, while those made from inferior recycled materials are hard, brittle and prone to breakage.
Youdaoplaceholder0 bottom and back structural strength .
The back of the composite elastic structure (with a thickness of 1.5-2mm) is treated by high-temperature vulcanization process and is difficult to tear by hand.
The adhesive backing must pass environmental protection certification, with no missed needles and even application of adhesive.
Youdaoplaceholder0 physical property testing
Youdaoplaceholder0 Motion performance : vertical deformation 2-5mm (50kPa pressure), sliding friction coefficient 0.4-0.7 (dry state).
Youdaoplaceholder0 durability :
The grass filament drawing force is no less than 50N, and the height loss after 50,000 wear resistance tests is no more than 10%.
After 2000 hours of UV aging resistance, the color difference ΔE is ≤4, and the strength retention is ≥80%.
Youdaoplaceholder0 environmental safety standards
Heavy metals (such as lead and cadmium) comply with GB 36246-2018, and the total volatile organic compounds (TVOC) are ≤0.5mg/m³.
There is no pungent smell of formaldehyde or benzene substances.
