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.
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.
How to become more professional for runway flooring?
- Higher impact absorption
- Ensure the availability of stable,lasting sports protection effect
- Lower vertical deformation
- Implement the runway to ensure professional athletic status
- Higher requirements for environmental protection
- Health and environmental protection mandatory constraint
