Granules spreading technology, the amount of granules and surface adhesive are twice that of traditional cast-in-place type, the wear resistance and durability of the product are significantly improved.
Granules spreading technology, the amount of granules and surface adhesive are twice that of traditional cast-in-place type, the wear resistance and durability of the product are significantly improved.
The initial bonding strength of the adhesive exceeds that of ordinary adhesives by more than 3 times, effectively preventing warping and hollowing.
The impact absorption and vertical deformation performance fully comply with the GB 36246-2018 standard, reducing joint injuries, alleviating muscle fatigue, and enhancing the sports experience. The sports performance is particularly outstanding.
Polyurethane prefabricated running track has excellent strength, folding-resistant and good toughness. It is not easy to crack or break even if it is squeezed by heavy objects or bent at will.
Mold foaming, rotary cutting, uniform thickness, error ±0.1mm.
On-site sampling is 100% passed the GB 36246-2018 standard. The product production and paving do not contain plasticizers, heavy metals, or any auxiliary agents. It is environmentally friendly, odourless, and does not hurt the human body.
Factory prefabrication ensures flatness, convenient construction, and greatly shortens the construction period.
