SPU Tennis Court Flooring Structure
1) (CS-6)Transparent finish layer
2) (TB-205T)Abrasion resistant layer
3) (TB-003T)springback layer
4) (TB-002T)buffer layer

The excellent performance: HARD TOP SOFT DOWN
The purpose of building sports courts is to ensure a professional, safe, healthy sports condition-the characteristics of hardness will bring the professional sporting feeling; the cushion effectively increasing the shock absorption and reduce the incidence of injuries to ankles, joints and ligaments. At the same time, it should reduce abrasion caused by falling and accident.
Features:
Stable Consistent Rebound
Effective Shock Absorption
Outstanding Skid Resistant
Facilitate Movements in Changing Direction
What is SPU?
It's a design based on human kinetics and physical characteristics flooring system, with hard top layer combined with soft rebound cushion lower layer structure. It's suitable to lay on concrete or asphalt substrates. The cushion layer is formed by single component modified polyurethane and top up with two-component modified acrylic resilience layer.
About SPU Acrylic Cushion Tennis Court
SPU acrylic tennis court system uses modified tenacious acrylic resin as the abrasion resistant layer. It's a breakthrough for the brittleness and fissility shortcomings of the traditional acrylic material.
Polymer compound material supports the surface layer well and its excellent ductility plays an effective role in dynamic anti-crack performance.
Then it combines with the permeation-type primer to form an integral rebound structure that has high adhesion and weatherability.
The prime coat isolates moisture underground and the layer has effective anti-seepage. Thus, all these ensure the floor durable.
The launch of SPU Tennis Court System is a complement to the shortcoming of the hard acrylic tennis court. Especially the sport protection which is provided by its resilience, it solves the sport harm to the athletes caused by the hard ground. At the same time, it further makes the ground provide more professional sport feeling for matches.
To promote the sport profession and protection advantage of the traditional acrylic floor
To improve the weakness of the traditional acrylic floor, durable and professional
The quality of the production is validated by international events and it is qualified by the State Administration of Environment Protection's product certification.

The performance comparison of different Acrylic tennis courts materials
| pavement materials | Base requirements | Competition performance | Environmental performance | durability | Usage limits |
| SPU material | Both cement and asphalt base | The hard upper and resilient under structure is special for tennis. The low modulus cushion layer at the bottom plays the most appropriate buffer effect. The high modulus strengthen layer in the middle provides sufficient compression rebound. The tenacity hard surface provides superior sport texture. The whole system ensures the tennis court has effective buffer, slip resistance to starting, moving and rebound performance. | Environmental. The product implements strictly the latest State Mandatory Standards of Indoor Decorating and Renovating Material and qualified in 'China Environmental Label(type I) by China's Ministry of Environmental Protection | The base coat and the cushion layer is airtight to isolate the underground moisture and prevent bubbling. The high extensibility prevent the tiny crack caused by deformation of the cement base. The surface is wearable, scratch-resistant, and uvioresistan. It is non-aging, color lasting and not easy to sand-out. Renovations, changing color or line are convenient. | It is suitable for both indoor and outdoor and not affected by any climate in principle. After rain, it just needs to clean the water on the surface and then put into use. |
| The traditional acrylic material | Asphalt base only | The new tennis courts have good sport texture in early stage. It is comfortable to start and the friction is stable. But the buffer absorption effect is bad. It has low resilience and lacks enough sport protection. The old one gets to harden and easy to cause injury to the athletes' joints. The sand consolidation effectiveness is worse. It sand-out easily and get to be smooth. | Environmental, odorless and non-toxic | Water resistance is not good. Low strength durability. Easy to sand-out. Low color durability. Need roll-coating renovation frequently to keep competition performance. The base material has low strengthen and easy to aging and harden. It is easy to conduct cracks on the surface. The low-priced products blend much more filler. Quality and performance change apparently. | Suitable for both indoor and outdoor. Dark soles are easy to produce friction marks on the surface. It is not easy to clear. Only if it is dry thoroughly can put into use. Otherwise, it is easy to damage the site. |
