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.
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.
