Wholesale Spu Rubber Basketball Tennis Sports Flooring for Gym/Stadium/Playground
Product Description
What is SPU?
In January, 2005,we spent three years developed and created a new product of cushion sports flooring,and 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 fore, 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 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.
