Product Description
About crystal basketball court
Innovation leading；Beyond the classic
Melt the charm of the crystal and SPU in one of the outstanding, professional sports and functional decoration
into a new generation of flexible stadium materials.
| 1· Original transparent water surface layer, high strength surface protection system is more excellent |
| 2· First colorful crystal wear-resisting layer, wear better, more outstanding visual Sand color patent structure, subvert the traditional, highlight the charm of crystal. |
| Sand color patent structure, subvert the traditional, highlight the charm of crystal. |
| The whole stadium will support, playing the upper hard lower elastic structure to extreme. |
| 3· The lining layer under the crystal wear-resisting layer,solve the trouble of marking is easy to wear. |
| 4· The background layer under the wear-resisting layer, won’t be worn, color will be more durable. Against UV effectively, giving the stadium higher and more stable weather resistance and discolour resistance characteristic. |
| 5· Strength of 6Mpa rubber rebound layer, the challenge of elastic material limit |
| 6· The construction process is more excellent, more stable adhesion |
| 7· Excellent permeable primer, stable and effective. |
Excellent performance
| Breaking the limits of traditional basketball court |
| 1· More professional
|
