SPU Tennis Sports Flooring

CN-S02 SPU Tennis Sports Flooring System

What is SPU?

In January, 2005,we spent three years developed and created a new product of cushion sports flooringand gave it a perpetual and dynamic name ‘SPU’. The same year in November, the State Trademark Office officially accepted the "Silicon PU "trademark applications.

Hence then, SPU started dominating in this new era for mainstream sports flooring construction. It has been implemented for the past 10 years and created a classic name for sports flooring.

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.

The excellent performance of SPU: 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.

Excellent Performance

1·Buffering effect given by res ilience protects the athletes joints and reduces sport injury.

2·The surface layer of acrylic cushion provides certain protection to accidental falls in sports.

3·The tennis court with buffering effect has a longer sport life.

4·The resilient tennis courts provide more stable ball speed and ball direction. The sport felling is better.

5·The surface layer of the acrylic cushion tennis court provides more comfortable sporting texture when athletes are starting, stopping abruptly or sliding.

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) 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.

Project Case

1.The tennis courts of ITF men's tour were paved with SPU acrylic flooring. (Completed in December 2009)

Very good counts, well built.  –Michael Fancutt

 (Comments from professional Tennis Player Federal’s coach Mr. Michael Fancutt)

2. Jiangmen Tennis Association (the winter training base of Chinese women’s tennis team) is paved with SPU Tennis Court System.
