Core parameters:
The standard thickness is 13mm, with a bottom layer of about 9mm (mixed PU glue+≤ 25% black particles), a middle layer of about 2mm (closed cell foam elastic layer), and a surface layer of about 2mm (self structuring spray coating). The impact absorption and vertical deformation comply with GB 36246-2018, with a skid resistance value of ≥ 47 (BPN 20 ℃), a measured tensile strength of 1.20MPa (national standard ≥ 0.5MPa), and a measured elongation at break of 130% (national standard ≥ 40%). The environmental standards comply with GB 36246-2018 (solvent-free).
Applicable scenarios:
Playgrounds in colleges and universities (preferred for cost-effectiveness and high frequency of use), athletics fields in primary and secondary schools (balancing performance and budget), community sports centers (for daily fitness and training), and general sports venues (for non professional events but meeting training needs). It is the optimal choice for school playgrounds, balancing good athletic performance with reasonable cost.

FAQ
Q1: What is the difference between a hybrid self structuring track and a fully plastic self structuring track?
A: The underlying materials are different. The full plastic bottom layer is made of pure PU (without particles), while the mixed bottom layer is made of PU glue and rubber particles. Full plastic molds have more uniform elasticity, better performance, but higher prices; Hybrid models offer higher cost-effectiveness and are suitable for budget limited projects such as schools.
Q2: Which is better, self textured surface layer or sprayed particle surface layer?
A: The self structuring surface layer forms anti slip patterns through chemical reactions, with no particles or shedding, and a longer service life; The sprayed particle surface layer contains EPDM particles, which pose a risk of particle dropping. Self structuring is a better choice.
Q3: Does the hybrid self structuring runway comply with the new national standard?
A: The Shengbang hybrid self structuring track adopts solvent-free materials and has passed all the testing items of the new national standard GB 36246-2018.
Q4: Is it suitable for use in cold regions?
A: Strong weather resistance, adaptable to weather conditions, and less prone to foaming. In extremely cold regions such as Northeast and Northwest China, it is recommended to increase the formulation of antifreeze agents. You can contact the Shengbang technical team for customization.
