Both the bottom and the top are made of polyurethane, with a polymer content of >90%, and have good resistance to compression deformation, bending and abrasion.
◎ Both the bottom and the top are made of polyurethane, with a polymer content of >90%, and have good resistance to compression deformation, bending and abrasion.
◎ Mold foaming, rotary cutting, uniform thickness. The rotary cutting seamless technology is used to standardize the automatic production process, accurately control the thickness, and the error is only ±0.1mm.
◎ The product absorbs 35%-38% of the impact, 1.2-1.5mm of vertical deformation, and the elongation at break is 2 times the GB 36246-2018 standard, and the tensile strength is 1.5 times.
◎ The TVOC index is far lower than the national standard. It does not contain plasticizers and heavy metals during the production and installation of the product, and no auxiliary materials are added during the construction process. It is less affected by the weather and has a short construction period.
