Product Description

Basketball Courts Volleyball Playground Sports Surface Silicon PU Rubber Flooring

 

Production Description


 

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.

 

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.
